High Performance:

The unique design and material properties of these seals provide design engineers with a new assortment of solutions to difficult applications.

Some of the more remarkable capabilities of the seal include:

High temperature service

High pressure ratings

Permanent elasticity with immunity to aging embrittlement and compression set.

Very low friction

Universal chemical compatibility

High speed service

Cryogenic service

PTFE seals have three basic design elements:

A pressure-actuated U-shaped jacket

A metal spring loading device

High performance polymeric seal materials

Spring energized seal lips and spring energizer are compressed when installed into the seal gland. The resilient spring responds with constant force, pushing out the sealing lips and creating a gas tight seal against the sealing surfaces. The seal expands as pressure is introduced – increasing the sealing force beyond that provided by the spring and the jacket material.
