FlexiSeal® Face Seals


Description

Creating a face seal gland can be as simple as cutting a groove in the face of the hardware and dropping the FlexiSeal® into it like an O-ring. The FlexiSeal® is designed to have a clearance fit on the non-pressure side of the seal so it will press easily into the groove. Of course it is not necessary to have a completely enclosed gland wall on the pressure side since the forces will never push the seal against that side of the groove. Face seals can be configured to seal internal pressure like in a pressurized chemical vat, or as an external seal like in a vacuum chamber.

Choosing the Right Design

Face seals are used in applications involving high pressures and temperatures, cryogenic fluids, corrosive media and other service conditions which exceed the limits of conventional elastomeric seals. Face seals are designed for either internal or external pressure. For internal pressure, the open side of the spring cavity faces the inside of the vessel. Fluid pressure actuates the seal lips. For external pressure, the spring cavity faces out (see illustration on Page 4-63 of the downloadable PDF).
