PFA Encapsulated Silicone O-ring

Encapsulated O-ring

• Function: Also known as an encased O-ring, encased O-ring, or Teflon-encased sealing ring, it combines the elasticity and sealing properties of rubber with the abrasion resistance and chemical resistance of FEP or PFA. The internal structure consists of silicone rubber or fluororubber coated with a relatively thin layer of FEP or PFA, offering superior chemical resistance and sealing performance compared to ordinary rubber, making it suitable for almost all harsh environments.
• Material: PFA coated with silicone.
• Temperature resistance: PFA -20°C ~ 260°C.
