Available with EPDM, NBR, silicone, and FKM cores, suitable for chemical processing, piping systems, and applications requiring both corrosion resistance and flexible sealing performance.

Taifno is a manufacturer and supplier of Type A PTFE Envelope Gasket, it is a cost-effective alternative to solid PTFE, combining the outer jacket’s broad chemical resistance (pH 0–14, against acids, alkalis, and solvents) with a flexible filler core that enhances compressibility and recovery. This design lowers material costs while maintaining reliable sealing performance in low-to-medium pressure chemical service.

Type B PTFE Envelope Gasket offers better sealing than Type A, lower cost than solid PTFE. It eliminates the weak point of Type A gaskets, prevents corrosive media attacks. Contact Taifno to get a customized solution, we can also offer technical support and free samples.
