It’s good to understand where and why couplings are used. • Pressure • Sleeve Lock • C onnect/Disconnect
• Couplings provide a means of quickly connecting and • Fluid Compatibility • Environment
• Temperature Under Pressure
disconnecting a line without a loss of fluid or entrance of air
into a system. If equipment needs to be assembled quickly
or if it needs routine servicing or repair, then a coupling is a
better choice for a fluid connection. Otherwise, you could end
up bleeding the entire system, damaging the system due to
contaminants, or dealing with a lengthy tear down and rebuild.
• When choosing couplings, there are a few key selection
criteria to keep in mind: the pressure rating of the
system, if there are pressure spikes, the media or fluid
being used for seal compatibility, and temperature.
