Product Description Product Description Product DescriptionPTFE Spring energized lip 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 spring energized lip seals have three basic design elements:A pressure-actuated U-shaped jacketA metal spring loading deviceHigh performance polymeric seal materialsSpring 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 FeaturesThe 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 frictionUniversal chemical compatibilityHigh speed serviceCryogenic service to -200 degrees CelsiusHigh temperature service to 280 degrees CelsiusHigh pressure ratings (over 30 Kpsi)Permanent elasticity with immunity to aging embrittlement and compression set.Design of Various PTFE Spring Energized lip sealsPTFE Spring Energized Lip Seals Jacket MaterialsMaterial CodeColourDescription & Recommended UseTemperature Range(oC)Tesile StrengthHardness(Shore D)Higdom? 100WhiteVirgin PTFE.
