PTFE Coated O-ring


The coated O-ring is a combination of the elasticity and sealing properties of rubber and the chemical resistance of Teflon. It is composed of silicone rubber or fluororubber inside and relatively thin Teflon FEP or Teflon PFA on the outside. This rubber combined with Teflon O-rings will provide excellent sealing properties.

    The structure of the encapsulation seal

    The manufacture of wrapped O-rings needs to pass strict quality control. By adopting a special technology, Teflon FEP polymer completely wraps the rubber inner core, and ensures that the O-rings have the required standard tolerances. The data used shows that we have a good quality commitment to the wrapped o-ring products, which is based on performance testing and strict quality control to ensure customer satisfaction and safe use of this product. Wrapped O-rings and any other rubber or pure Teflon O-rings have unparalleled tightness and long life in one respect, especially in harsh media.
