Spring-Energized PTFE Reciprocating Seals - Spring Reciprocating Seal

Reciprocating Seals

Why Spring-Energized PTFE Reciprocating Seals?

The Performance Sealing spring energized reciprocating seals replace conventional elastomeric O-rings and U-cups where the service conditions are beyond their operating capabilities. They can be designed, engineered, and machined to fit a variety of different applications to meet your needs. Additional benefits of using reciprocating seals include: 

  • Self-Lubricating and can be used in dry environments.
  • Excellent chemical compatibility for a variety of different applications.
  • The Spring Enhances Performance by:
    • Allowing for tolerance variation
    • Overcoming thermal expansion/contraction
    • Compensating for wear to increase the useful life of the seal.

Temperature & Pressure Range

Our reciprocating seals operate in a wide range of temperatures and pressure conditions.

  • Temperature Range from -450°F to 600°F (-268°C to 315°C)
  • Pressure Conditions from High Vacuum to High Pressure (50,000 psi)*

What are Duruseal® Spring-Energized Reciprocating Seals?
