| Message: | PTFE backup rings (PTFE back-up rings) are used for static and dynamic applications. It's better used for static sealing applications with corresponding O-ring.The use of PTFE backup ring will help control O-ring extrusion in high pressure applications. PTFE backup rings are compatible with all hydraulic fluids,Website:http://www.rayflon-seals.com, since they are virtually chemically inert, and also can be used in applications involving elevated operating temperature conditions. In addition, PTFE backup rings can greatly improve O-ring performance and extend service life, even if extrusion does not present a problem.Materials: 100%virgin PTFE for light and medium load requirements.PTFE with filler (Glass /Graphite /Carbon /Bronze)for greater load requirements.Temperatures:-150~+250 degree celsiusThree basic Types for PTFE backup rings(PTFE back-up rings): Scarf cut Spiral cut UncutSpecifications:From ID3mm to ID500mm can be produced, tolerance can be controlled within +/-0.03~+/-0.1mm.Advantages: 1Low MOQ:It can meet your business very well2OEM accepted:Just provide drawing or sample3Good service:We treat clients as friends4Good quality:We have strict quality control system.
