Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.
PTFE seals have three basic design elements:
Spring energized PTFE seals is a spring-energized U-cup that uses a variety of jacket profiles, spring types and materials in rod and piston, face and rotary seal configurations. They are used when elastomeric seals fail to meet 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 alloys, including stainless steel, Elgiloy and Hastelloy.
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 spring energized PTFE seal include:
