SHoelaodserle® G seal for rods/glands & pistons

Rod / gland seals Solosele® G

Robust single element seal

Description
Solosele® G is our compact rod/gland

saves space without compromising its
high integrity sealing capabilities.

Standard versions comprise a profiled
elastomeric sealing element that is firmly
protected by an integral anti-extrusion
element of rubber-proofed fabric. High
integrity sealing is enhanced by its flexible
chamfered lips.

For general duty hydraulics

Description
Lionsele® U2 is a compact U-profiled
rod/gland seal of high-performance
polyurethane. Its asymmetrical design
ensures sealing integrity when cylinder
rod/ram deflections occur.

In operation, the secondary sealing lip
traps fluid behind the primary sealing
lip and serves to increase lubrication.
This prevents dry running, thus reducing
the risk of stick-slip action. Seal life is
significantly increased by the optimised
fluid film conditions created beneath the
primary sealing lip.

Composite seals — special duty

Composite seals Special duty products

Custom-designed for specific rod/gland or
piston applications

Description
In addition to our standard ranges
of Lionsele® G and Lionsele® P,
we regularly custom-design and
manufacture hard-wearing compact
composite seals to work to specific
operational parameters with our
customers’ hydraulic and pneumatic
plant. These can be piston or
rod/gland seals.

Most of these seals comprise a sleeve of
high-performance PTFE — such as our
Fluolion® Xtreme — that is supported and
energised by an elastomeric element.
