Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions where conventional washers fail. The white PTFE material provides exceptional chemical resistance against aggressive solvents, acids, and bases, making it ideal for chemical processing, pharmaceutical manufacturing, and food processing equipment. Its remarkable 500°F maximum temperature rating ensures reliable performance in high-heat environments including automotive, aerospace, and industrial oven applications. The 7/16" screw size compatibility combined with precise 0.469" ID and 0.922" OD dimensions creates optimal sealing surfaces while the Durometer 55D hardness maintains sealing integrity under vibration and thermal cycling conditions. These flat washers serve as essential components in preventing galvanic corrosion, reducing friction, and providing electrical insulation in complex assembly systems.
