Spring Energized

Spring Energized PTFE Face Seals

The GFS Spring Energized Face Seal is designed for applications with high pressures and temperatures, cryogenic fluids, extreme media and other service conditions which exceed the performance characteristics of O-rings and conventional elastomeric seals. Face Seals are designed for either internal or external pressure, but not both. For this external pressure design the open sealing cavity faces outwards. Typically, the gland design for face seals is the same as an O-ring.

When designing a seal gland typical extrusion gaps are 0, but can be as high as 0.003” without impacting the performance of the seal. This seal comes installed standard with a V-Spring. Higher pressure levels can be attained with the utilization of a PTFE back-up ring.

Static Sealing applications can be very demanding depending.  GFS Engineers are available to consult on any application.  Click here to contact a GFS Engineer.
