Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions where conventional washers fail. The white PTFE material maintains structural integrity under extreme thermal cycling up to 500°F, making it ideal for chemical processing equipment, high-temperature manufacturing systems, and aerospace applications. Its exceptional chemical resistance prevents degradation when exposed to aggressive solvents, acids, and bases, while the 0.656" ID and 1.25" OD provide precise dimensional control for 5/8" screw installations. The Durometer 55D hardness ensures optimal compression for effective sealing in flange connections, pump assemblies, and valve systems where fluid containment is critical. These properties combine to reduce maintenance frequency, prevent system contamination, and enhance operational safety in demanding industrial environments.
