Why Spring-Energized PTFE Reciprocating Seals?
- Spring energized seals replace conventional elastomeric O-rings and U-cups where the service conditions are beyond their operating capabilities
- Self-Lubricating and can be used in dry environments
- Wide Operating Temperature Range from -450°F to 600°F (-268°C to 315°C)
- Pressure Conditions from High Vacuum to High Pressure (50,000 psi)*
- Excellent Chemical Compatibility
- Designed, Engineered, and Machined to fit
- The Spring Enhances Performance by:
- Allowing for tolerance variation
- Overcoming thermal expansion/contraction
- Compensating for wear to increase the useful life of the seal.
What are Duruseal® Spring-Energized Reciprocating Seals?
Duruseals® are composed of a Duron® seal jacket and an energizer. We offer a wide range of Duron® and energizer materials, as well as configurations to satisfy your conditions and parameters. For a complete proposal, submit a request for quote and we will respond, immediately.
|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.
