Carbon Fiber Filled PTFE Spring Energized Seals

Product DescriptionThe Spring Energized PTFE Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other polymer) seal partially encapsulating a corrosion-resistant metal spring energizer. The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment. MaterialPTFE filled with bronze(glass, graphite, carbon, etc. ) Application ExampleRadial Seals in Static Service. Radial Seals in Reciprocating Motion. Radial Seals in Rotary Motion. Inside face Seals in Static and rotary Service. Outside face Seals in Static and rotary Service. Section structureSymmetric, for Rod, for Piston are available. Spring type:U shaped spring(Type 400) Round wire spring (Type APS) O shaped spring (Type 103) GrooveStandard Heel Groove.
