Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical performance advantages in demanding industrial applications where conventional washers fail. The white PTFE material provides exceptional chemical resistance against aggressive fluids and solvents, while maintaining structural integrity at continuous temperatures up to 500°F. Engineered for 1/2" screw size applications, these washers solve common challenges in chemical processing, food manufacturing, and high-temperature equipment where metal washers corrode or gall. The Durometer 55D hardness offers the perfect balance between compliance and durability, protecting sensitive surfaces from damage while ensuring reliable load distribution. Their low coefficient of friction makes them ideal for applications requiring repeated assembly/disassembly without seizing or binding issues.
