Product Description

 
Product Description

PTFE/PEEK piston 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/PEEK piston seals have three basic design elements:

  • A pressure-actuated U-shaped jacket
  • A metal spring loading device
  • High performance polymeric seal materials

Spring energized 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.

 
Key Features

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 seal include:

  • Very low friction
  • Universal chemical compatibility
  • High speed service
  • Cryogenic service to -200 degrees Celsius
  • High temperature service to 280 degrees Celsius
  • High pressure ratings (over 30 Kpsi)
  • Permanent elasticity with immunity to aging embrittlement and compression set.
