Expertly Engineered for High-Performance Industrial Applications.
At Stephens Gaskets, we specialise in manufacturing expanded PTFE washers, delivering high-performance sealing solutions for industries requiring exceptional chemical resistance, flexibility, and durability.

Why Choose Expanded PTFE Washers?

As experts in sealing solutions, we know industries need reliable, long-lasting gaskets that withstand harsh chemicals, extreme temperatures, and fluctuating pressures.

Designed to perform in extreme conditions, our ePTFE washers offer superior compressibility, making them the ideal choice for sealing irregular surfaces, reducing leaks, and ensuring operational efficiency in demanding industrial environments.

Our expanded PTFE washers are engineered to meet these challenges with outstanding benefits:

  • Unmatched Chemical Resistance: Performs in aggressive environments exposed to acids, alkalis, solvents, and hydrocarbons.
  • Extreme Temperature Tolerance: Withstands -240°C to +260°C, ideal for cryogenic and high-temperature applications.
  • Superior Sealing Performance: Conforms to rough or irregular flange surfaces for leak-proof sealing under low bolt loads.
  • FDA-Approved & Hygienic: Safe for food, pharmaceutical, and cleanroom applications.
  • Non-Stick & Low Friction: Prevents material buildup, ensuring efficiency in sterile and high-purity environments.
  • Long-Lasting & Low Maintenance: Resists aging, UV exposure, and oxidation for cost-effective performance.
