FEP And PTFE Encapsulated Coated O Ring

FEP and PTFE Encapsulated Coated O Ring

FEP Combining the elasticity and sealing of rubber with the chemical resistance of Teflon, it is composed of a silicone or fluorine rubber inner core and a relatively thin Teflon FEP or Teflon PFA outer cover. This rubber Teflon sealing ring Has excellent sealing performance. Rubber O-rings are easy to wear, chemically resistant and gas-permeable. Pure Teflon O-rings have higher hardness and can resist compression but have poor elasticity.

Main advantages: 

outstanding chemical resistance, suitable for almost all chemical media: excellent corrosion resistance, good compression resistance, good swelling resistance, high temperature resistance, and a wide range of temperature applications. 

Applicable temperature range: 

Teflon FEP Shell: -60℃-205℃ can be used for a short time under 260℃ high temperature. Teflon PFA shell: -60℃-260℃ can be used for a short time under 300℃ high temperature. 

Uses: pumps, valves, mechanical seals, filters, reaction vessels, pressure vessels, heat exchangers, boilers, pipeline flanges, gas compressors.
