Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions for demanding industrial environments where conventional washers fail. The white PTFE material provides unmatched chemical resistance against aggressive solvents, acids, and bases, making it ideal for chemical processing equipment, laboratory apparatus, and pharmaceutical manufacturing. Its remarkable 500°F maximum temperature resistance ensures reliable performance in high-heat applications including automotive systems, industrial ovens, and thermal processing equipment. The flat washer design with precise 2" OD and 0.39" ID dimensions creates effective sealing surfaces for 3/8" screw size applications while the inherent low friction characteristics of PTFE prevent sticking and facilitate maintenance in frequently disassembled joints. These properties combine to solve common industrial challenges including thermal degradation, chemical corrosion, and electrical insulation requirements.
