Professional Applications & Engineering Value

Engineered for extreme condition performance, these PTFE plastic flat washers deliver critical solutions where conventional washers fail. The white PTFE material provides exceptional chemical resistance against aggressive solvents, acids, and bases, while maintaining structural integrity in temperatures reaching 500°F. This makes them ideal for high-temperature sealing applications in chemical processing equipment, food manufacturing machinery, and semiconductor manufacturing. The Durometer 55D hardness offers the perfect balance between compression resistance and sealing capability, ensuring reliable performance in industrial insulation and electrical isolation scenarios. Their inch system measurements (0.375" ID x 1.25" OD) provide precise compatibility with standard 3/8" fastening systems, eliminating installation issues and reducing maintenance downtime.

Specification Summary & Compliance
