Our Company:

Aerofit Products was formed on September 5, 1968 and APT Laboratories was
established as a hydro-mechanical testing laboratory in March 1972.
In March 2004 Aerofit Products and APT were acquired by the present owners
and renamed Aerofit, Inc.
Aerofit and APT have grown into one of the largest suppliers of standard and spe-
cialty fittings in the world. Our manufacturing and testing facilities now encom-
pass over 67,000 square feet.
Aerofit designs, manufactures and tests thousands of parts for application in mili-
tary aerospace, commercial aerospace, marine and nuclear markets. In addition to
proprietary parts, we also produce parts to customer specifications, and industry
standards.
Our goal is to supply our customers with economical, high quality fluid fitting sys-
tems and information through a modern production facility and responsive cus-
tomer support network.
Since it was founded, Aerofit has demonstrated its commitment to quality through
continuous improvement in its production and product support processing.

The SMA Fitting System

The SMA Fitting System

The SMA product line is a high performance fluid fitting system using the unique characteristics ofTinel, a shape
memory alloy material.

Many metals exhibit a phase change as they are heated and cooled. We can illustrate
this using a crude ‘stick and ball’ model of the metallic lattice.

The phase change is an instantaneous shear transformation between a body centered
cubic structure called austenite and a highly twinned martensite structure.

Shape Memory Alloys are a special class of alloys which not only change phase on
cooling or heating but have the particular characteristic of a low temperature phase
which gives the appearance of increased ductility.

Austenite Martesite The higher temperature austenitic structure
has the characteristic stress strain curve of
most metals.

Stress The lower temperature martensitic structure
has a stress strain curve more like that of an
elastomer in which there is a ‘plateau’ stress.

24 68 All the deformation up to about 8% is “elastic” or in other words it can
be recovered but not by simply relaxing the stress while in the marten-
Strain% sitic condition.

Let’s go back to the ‘stick and ball’ model. We cool the material and it becomes martensitic. It does not change
shape by being cooled, but we can now deform it mechanically. If it stays cold it will remain deformed, but if
we allow it to warm up, the austenitic structure reappears and the material returns to its original shape.

This cycle from austenitic to martensitic to deformed martensitic and Cool
back to austenitic is repeatable indefinitely and is what we call ‘free re-
covery‘. It is important to note that it is a one way process.

At Aerofit a Tinel coupling or separable
end fitting is machined at room tempera-
ture, in its high strength (austenitic) state, Deform
to an inside diameter slightly smaller than Warm
(max 8% strain)

the pipes or tubes it is to join. The com-
ponent is then cooled in liquid nitrogen
and the metallurgical characteristics of the alloy change to a lower strength (mar-
tensitic) state. With the coupling in this lower strength, cooled state, a tapered
mandrel is driven through its center, expanding the inside diameter of the cou-
pling.

Liquid Nitrogen Bath The coupling remains in cold storage in its expanded condition until ready for
use. It is then removed from this container and slipped over the tube or pipe ends
to be joined. As the coupling warms to room temperature, it reverts back to its
high-strength state and attempts to recover to its original shape while exerting
tremendous radial force. This permanent, live crimp action establishes a leak free, metal to metal seal between
the coupling and the tube or pipe throughout the life of the joint.

This product line includes permanent couplings called CryoFit and separable end fittings called CryOlive (flare-
less) and CryoFlare (flared). CryoFlare is also available in a lightweight version.

The SMA Fitting System is designed for use on 2000, 3000, 4000, and 5000 psi hydraulic systems that incor-
porate titanium, stainless steel, and aluminum tubing materials.The SMA Fitting System is easier and less costly
to install than such traditional joining methods as welding, brazing, and swaging. It meets or exceeds the burst,
impulse, and fatigue requirements of welded or brazed joints.

SMA FITTING SYSTEM BENEFITS:
Aerofit, Inc.’s SMA fitting system is an excellent example of a product that helps customers dramatically reduce
traditional assembly process costs and offers many advantages such as:

1. No expensive tooling
2. Limited access capability
3. No leaks
4. Light weight
5.Visual inspection
6. Quick & easy installation
7. Technical support
8. No hot work or flushing
9. No X-ray

1. No expensive tooling - Since installation tools are not required, SMA fittings can be installed with equal ease
on or off an aircraft, producing separable or permanent joints of the highest quality and reliability.
In comparison with alternative methods, process throughput increases have been demonstrated without any
additional investment in manpower or capital. Dramatic reductions in production flow time, manufacturing
labor and required skill level are achievable.

2. Limited access capability - Installation of a the SMA Fitting System can be easily achieved in densely packed,
tight access areas due to the unique toolless package. The installer needs only his/her hand, which allows for
simple installation in any area accessible by the installer’s fingers.

3. No leaks – The SMA Fitting System’s product lines are tailored to the demanding performance requirements
of the aerospace industry. It has been thoroughly tested and approved and meets or exceeds high-performance
aircraft fitting requirements, including AS18280, AS85421, AS85720, and major OEM specifications. The
CryoFit coupling is rated up to 5000 PSI working pressure, and provides a highly reliable metal to metal con-
nection that is both leak proof and permanent.

4. Light weight – Since no bulky tooling is required designers can eliminate the need for “tool access” bends.

The SMA system can be installed adjacent to bends because no tool en- Reduced Tube Length
velope spacing is required allowing the designer to reduce tube length
and system weight.

As a reference the CryoFlare and CryOlive end fittings are about 10% Axially Swaged
lighter than a comparable welded on fitting.

5. Visual Inspection – Preparation, installation, and inspection of a SMA
joint takes only seconds, reducing overall installation costs and produc-
ing a superior joint. Dissimilar pipe and tube materials may be con-
nected to each other, since Tinel does not support galvanic corrosion.
Additionally, tubes with different wall thicknesses can be connected.

6. Quick & easy installation –The installation of an SMA fitting takes about SMA
5 seconds. Operators with minimal training easily install SMA fittings,
producing consistent results. No bulky swaging tools or welding equip-
ment are required.The entire pipe or tube preparation, installation and
inspection of a joint takes only minutes and is a fraction of the time required for welding or brazing

7. Technical Support – Requests for quotes or general pricing information are handled quickly. Aerofit, Inc.
encourages customers to call for answers to technical questions on applications, installation and product
design. Prompt response to these inquiries is aimed at the most proficient and cost effective use of Aerofit,
Inc.’s products

All of Aerofit, Inc.’s products are evaluated and qualified in the company’s own testing facilities and indepen-
dent laboratories. Validation of product performance is proven through extensive testing of sealing integrity,
flexure fatigue, impulse and burst strength. Product quality, reliability and consistency are ensured by careful
control of raw materials and the use of statistical process control during machining. Aerofit, Inc. also main-
tains complete documentation and traceability at each step of the manufacturing process. The company is
both NADCAP and AS9100 certified.
8. No hot work or flushing – Unlike welding and brazing, SMA Fitting installation presents no danger of damage
to neighboring components from flame or splatter. It produces no contaminants, so does not require fume
extraction. Since it is installed directly on clean pipe or tube without contamination of the system by flux,
slag or oxides, there is no need to flush the system.
9. No X-ray - Inspecting the SMA installation simply requires verifying that the fitting lines up with the prein-
stallation position marks. It does not require x-ray certified inspectors or expensive equipment.

Couplings & Compatibles

COUPLINGS AND COMPATIBLES - CRYOFIT

CryoFit Couplings Introduction

CryoFit couplings and CryoyFit Compatible fitting shapes are
complete systems used in joining aerospace tubing. The CryoFit
fitting system combines superior performance and high reli-
ability with easy installation and inspection. The CryoFit sys-
tem consists of SMA couplings and a wide array of non SMA
shape fittings (tees, elbows, crosses, etc.).

The compact, one piece CryoFit coupling is manufactured

from Tinel, a nickel-titanium alloy with shape memory char-

acteristics.

CryoFit Compatable CryoFit Compatible fittings are manufactured from titanium,

and in conjunction with the CryoFit coupling, they produce a

complete system. An extensive selection of fittings is available for both separable and permanent connections.

CryoFit Couplings are installed by simply positioning the coupling at a tube joint or tube and CryoFit Compat-
ible fitting leg, and allowing the coupling to warm from its cryogenic storage temperature. As it warms, the
coupling shrinks and crimps down on the tube or compatible fitting with tremendous radial force, forming a
permanent, metal to metal seal by coining the surface of the tube.

CryoFit couplings are easier and less costly to install than traditional joining methods such as welding, brazing
and swaging. Installation of a CryoFit coupling can be easily achieved in densely packed, tight access areas due
to the unique tool less package. The package allows for simple installation in any area accessible by the installer’s
fingers. Preparation, installation, and inspection of a CryoFit joint takes only seconds, reducing overall installa-
tion costs.

The shape memory capability of Tinel ensures that the couplings always Expanded couplings have an inside

CryoFit fitting systems meet or exceed high performance aircraft fitting
requirements, including AS85421, AS85720, AS18280, ISO7169 and outside diameter
OEM specifications.

The accuracy of a CryoFit installation is easily verified. A quick visual
inspection ensures that the couplings have been properly positioned.

The CryoFit fitting systems have an outstanding record of over 39 years As the coupling warms and recovers

SHAPES

I. INTRODUCTION

CryoFit couplings are used to permanently join hydraulic and pneumatic tubing. A one piece union, the
CryoFit coupling is made with an alloy called Tinel that has shape memory properties. The couplings are
shipped and stored in liquid nitrogen prior to installation. Upon receipt, the CryoFit coupling will have an
inside diameter which is larger than the outside diameter of the tubes to be joined. When the coupling is
removed from liquid nitrogen, slipped over the two tube ends and allowed to warm to room temperature,
it will shrink to an inside diameter which is smaller than the outside diameter of the tubes. Compression of
the tubes will occur and a permanent connection will result.

CryoFit couplings should be removed from their storage containers and installed only by personnel who have
been properly trained in the handling of liquid nitrogen and CryoFit couplings. Please see Section D for stor-
age, handling and safety of liquid nitrogen.

II. INSTALLATION TOOLS

CryoFit couplings are installed using simple tools. The function of each tool is described as follows:

1) CRYOFIT INSTALLATION PACKAGE (Figure 1): An outer shell sur-
rounding each coupling enables the installer to grasp the coupling
during installation and also insulates the coupling during installation,
thereby extending the installation time. Once installed the package is
removed and discarded.

2) TEST COUPLING (Figure 2): Used to: Figure 1
a) Ensure proper tube alignment CRYOFIT
b) Check the gap between the tube ends COUPLING IN
c) Check the O.D. of the tube for proper size INSTALLATION

III. PREPARATION FOR INSTALLATION

Ensure the couplings have been stored properly and the tubes are properly prepared. If a coupling shrinks before
being installed on a tube, it should be returned for re-expansion.

III(a) INSPECTION OF COUPLING INSIDE DIAMETER (I.D.)

If there is reason to believe that a coupling has been warmed (perhaps because of a low liquid nitrogen level in
the dewar or previous removal from liquid nitrogen), its I.D. can be checked as follows:

1) Obtain a length of the same size tubing as the coupling, approximately 6 inches long.

2) Cool the end of the tube in liquid nitrogen until boiling stops.

3) Being careful to keep the coupling in the liquid nitrogen, insert the tube into the coupling. The tube
should easily slip through the entire bore of the coupling.

4) If the tube cannot pass through the coupling, the coupling should be removed from stock and returned
for re-expansion.

III(b) TUBE PREPARATION

The following steps will ensure that the tube is properly prepared for the coupling installation. This procedure
describes the replacement of existing tube sections as well as new installations on the aircraft.

1) Mark the tube at the point where cuts must be made to remove the damaged section. Generally, a length
of straight tube equal to the coupling length must remain after the damaged section is removed.

2) Cut the tube at the marks, using a roller type cutter to avoid generating chips which could contaminate
the system. Deburr the tube ends.

3) Cut and deburr a splice tube to replace the damaged section which has been removed. The splice tube
should butt against the remaining tube ends if possible. A maximum gap of .120 inch between the tube
ends is permissible.

4) Inspect all tube ends to be sure they are free of burrs and conform to any applicable specifications.

5) Tubing within 1/2 coupling length of the end should be free of deep scratches. If necessary, scratches
can be removed by polishing with 400 grit or finer abrasive in the circumferential direction.

IV. INSTALLATION PROCESS

The processes for installing couplings, elbows, tees and fittings are similar. With fittings, some steps are re-
peated.

IV(a) TUBE TO TUBE INSTALLATION

1) Obtain the proper CryoFit couplings and installation tools.

2) Clean and dry any hydraulic fluid from the tube ends which might interfere with marking the tubes.

3) Slip a test coupling over the tube ends to ensure that the tubes are round and free from burrs. The test
coupling should slide freely.

34 www.aerofit.com

4) Position the test coupling so that both tubes are visible in the coupling window. The tubes should be
butted together if possible; however, if both tubes are visible, the gap is deemed acceptable (less than .120”
or 3mm).

5) Several methods are available for marking the tube to insure the proper positioning of the coupling. Two
methods of tube marking will be discussed. The first method uses a marking gauge and a pen to mark a
band on each tube at the proper distance from the end. Place the marking gauge over the tube end. Using
the marking pen, color the tube in the rectangular slot in the marking gauge. Repeat the process on the
other tube (Figure 8).

When you do not have a markingMgAaRuKgINe,GtPhEeNtubes can be pre-marked with an installation band by
measuring the distance from the end of the tube. In this method the installation band is marked around
each tube at the proper distance from the end (See Figure 9).

6) To aid in positioning the coupling, place an installation stop in the middle of the mark. Check the location
by positioning the test coupling so that it is butted against the stop. Both tube ends should be visible in the
window and the test coupling should cover approximately half the installation mark on each tube (Figure
10). Adjust the tubes and installation stops if necessary. Remove the test coupling.
FIGURE 10

INSTALLATION MARK

INSTALLATION STOP

7) Tube chiller use is optional but, recommended for sizes 04 through 08 and for aluminum tubing. Place
cooled tube chiller over the tube to be joined (Figure 11). Remove the chiller after 20-30 seconds. As an
alternative, spray the tubes with liquid nitrogen using the Spray Chiller Bottle. Spray the tubes (1-1/2)
coupling length on both tubes) for 20 to 30 seconds. Placing the CryoFit coupling in contact with a tube
which has not been pre-chilled with liquid nitrogen may initiate premature warming and shrinkage of
the coupling.
FIGURE 11

TUBE CHILLER

8) The following steps should be performed sequentially and without delay:
a) Cool the tubes to be joined and remove the chiller if used.
b) Using cooled tongs, remove the CryoFit installation package from the liquid nitrogen and grasp the
package between the thumb and forefinger.
c) Deflect the tube without the installation stop to allow the coupling to be slipped over the end.
d) Slip the coupling onto the tube, realign the tubes and slide the coupling against the installation stop
(Figure 12).

e) Check to see that the coupling is against the installation stop and that the deflected tube has been inserted
into the coupling to the installation marks (Figure 13).
FIGURE 13

INSTALLATION MARKS

f) Allow the coupling to warm and shrink onto the tube. Remove the CryoFit installation package and the
installation stop.

g) Verify that both ends of the coupling lie within the installation marks on both tubes (Figure 13). If one
or both ends do not touch the installation marks, the installation is incorrect and must be removed.

IV(b) INSTALLATION OF FITTING TO TUBE:

Tees, elbows, and other fittings are installed by connecting each leg of the fitting to a tube with a CryoFit cou-
pling. The installation procedure is similar to that used in connecting two tubes.

1) Obtain the proper CryoFit couplings, installation packages, fittings, and installation tools. With the fitting
in position, the gap between the fitting legs and the adjoining tubing must be less than .120 inches or
3mm. The test coupling should be used to ensure this gap. Refer to Section IV (a), Step 4.

2) On all fitting legs to be joined, slip an O-ring over each fitting leg and place in the center of the etched
installation band (Figure 14).
FIGURE 14

O-RING

3) Position the fitting so that all legs are aligned with the tubing. Slip a test coupling over each fitting leg. The
test coupling should slide freely. With the test coupling butted against the O-ring, the fitting leg and tub-
ing ends must be visible in the test coupling window and the opposite end of the test coupling must fall

37 www.aerofit.com

within the installation mark on the tubes. Adjust the tubes and O-rings if necessary (Figure 15). Remove
the test coupling from one leg.

FIGURE 15

FITTING LEG AND TUBE TEST COUPLING
END MUST BE VISIBLE
IN EACH WINDOW

4) Using one or more tube chillers, cool the tube and one leg of the fitting. Leave the remaining test couplings
in position on the other leg(s) to ensure proper positioning. Additionally, the spray chiller bottle can also
be used to cool the leg and tubing.

5) The following steps should be performed sequentially without delay:
a) Remove the tube chiller(s), if used, from the leg to be joined.
b) Remove the CryoFit installation package from liquid nitrogen with pre cooled tongs and grasp the
package between thumb and forefinger.
c) Deflect the tube and slip the coupling over the tube.
d) Realign the tube. Slide the coupling against the O-ring on the fitting leg (Figure 16).

FIGURE 16

e) Check to ensure that the coupling has been properly positioned against the O-ring, and that the tube
has been inserted into the coupling to the installation mark. Also be certain that the remaining fitting
legs are in proper alignment; adjust if required (Figure 17).

Design Guide CRYOFIT PRODUCTS

1.0 Introduction

Good design practices, common to all tubing systems, should be followed when using CryoFit fittings.
The use of these couplings will allow lines to be spaced closer together while still maintaining the nec-
essary access for installations.

2.0 Installation Clearance

In designing a tube system using CryoFit couplings, the assembly technique must be considered to assure
that sufficient space is provided for coupling installation. It is this installation clearance which limits the
spacing of adjacent hydraulic lines and components. The CryoFit system often allows a closer spacing than
alternate methods. The spacing and clearances noted in this document are the minimums recommended
for standard CryoFit installations.

2.1 Radial Clearance

The clearance required between CryoFit coupling installations is determined by the clearance required for
removal of the installation package. The required clearance between two parallel tubes is listed in Figure 1.

2.2Axial Clearance
The amount of axial clearance and straight unobstructed tube required will vary with coupling size and
the installation technique employed.
Proper installation requires that a length of tube equal to 1/2 the coupling length be inserted in each end
of the coupling. The coupling can be positioned either by axially moving the tube to allow access or by
deflecting the tube.
2.2.1 Axial Tube Movement
In this installation technique, one tube is pulled back axially to allow the installation of the coupling.
The coupling is slipped into place on the second tube and the first tube is then inserted into the cou-
pling (See Figures 3A and 3B). This method requires the minimum amount of straight tube, 1/2 the
coupling length, but requires axial tube movement.

NOTE: The area from the end of T1 to the obstruction should be equal to the length of the coupling.
2.2.2 Tube Deflection
As an alternate to moving the tube axially the tube may be deflected to one side. The coupling is
then slipped over the deflected tube. The tube is repositioned and the coupling is slipped into place
(See Figure 4). This method eliminates the need for axial tube movement, but requires a full cou-
pling length of unobstructed tube on one end.

Separable End Fittings

SEPARABLE END FITTINGS - CRYOLIVE (FLARELESS)
AND CRYOFLARE (FLARED)

Introduction:

The CryOlive and CryoFlare sleeves and corresponding nuts come preasem-
bled in a plastic installation package. This assembly has many functions. It
acts as an installation tool, inspection gauge, dust cap, and protective cov-
er for the tube end. Accurate placement of the assembly is automatically
ensured and provides for correct tube position equal to that of internally
swaged flareless and flared sleeves. Because the installer needs no tools, SMA
fittings assemble with equal ease in the shop or on the aircraft.
At installation, this assembly is removed from liquid nitrogen, slipped onto
the end of the tube, and allowed to warm from its cryogenic storage temperature. In seconds, the shape memory
CryOlive (flareless) and CryoFlare (flared) end fittings shrink and crimp down on the tube with tremendous
radial force, producing a leak proof metal to metal seal between the tube and sleeve. The plastic installation
package acts as an installation tool, inspection gauge, dust cap and protective cover for the tube end.

The time required for both training and product installation is a small fraction of that needed for internally or
externally swaged sleeves. Regardless of the installer’s skill level, installation is accomplished in a few seconds.
CryOlive (flareless) and CryoFlare (flared) end fitting assemblies are installed by hand. No capital expenditure
is required.
After installation, a visual inspection is all that is needed. The inspector has only to look at the end of the as-
sembly to determine that the tube is visible in the inspection window (CryOlive) or that the tube is at the stop
(CryoFlare) to determine that the installation is correct.
The CryOlive (flareless) and CryoFlare (flared) end fittings use the same shape memory technology as the
CryoFit fitting system, which has a service record of more than 25 years in the aerospace industry with no re-
ported inservice failures. During qualification, CryOlive (flareless) and CryoFlare (flared) end fittings met or
exceeded the requirements in AS18280 and other demanding aircraft manufacturers’ requirements.
