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?

|Duruseal® F: Finger Spring Reciprocating Seal||
Finger spring reciprocating seals are suited for sealing viscuous media as the load is applied to the edge of the sealing lips.
|Duruseal® H: Helical Spring Reciprocating Seal||
Helical spring reciprocating seals are suited for slow service, cold and vacuum service.
|Duruseal® AC: Angled Coil Spring Reciprocating Seal||
Angled coil spring seals are suited for low friction, small inside diameter cross sections and best at compensating for tolerance variation, and overcoming jacket wear.
|Duruseal® R: Ribbon Spring Reciprocating Seal||
Ribbon Spring reciprocating seals are suited for extreme temperatures and hardware tolerance variations.
|Duruseal® O: Duraz™ Elastomeric O-ring||
Elastomeric O rings are best suited to minmize dead volume and provide a metal free seal.
