PTFE FlexiSeal®
The FlexiSeal is a spring-energized U-cup utilizing a variety of jacket profiles, spring types and materials in Rod & Piston, Face and Rotary seal configurations. FlexiSeals are used where elastomeric seals fail to meet the temperature range, chemical resistance or friction requirements. Jacket profiles are made from PTFE and other high performance polymers. Spring types are available in corrosion-resistant metal alloys, including stainless steel, Elgiloy® and Hastelloy®. Standard FlexiSeals are precision machined to fit inch/fractional and MIL-G-5514 glands. Standard and custom sizes in multiple geometries are available from 1/8" to 72" diameters.

FlexiSeal Face Seals

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.

Applications
The FlexiSeal Face Seal’s advantages over conventional elastomeric seals make it ideal for many applications including:
