Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions where conventional washers fail. The PTFE material provides exceptional chemical resistance against aggressive solvents, acids, and bases, while maintaining structural integrity at continuous temperatures up to 500°F. The 0.812" ID ensures precise alignment with 3/4" screws, preventing installation issues and material stress. With Durometer 55D hardness, these washers offer the perfect balance between compression resistance and sealing effectiveness, making them ideal for chemical processing equipment, high-temperature machinery, food manufacturing systems, and semiconductor manufacturing where contamination must be avoided. The 2.25" OD provides substantial bearing surface to distribute clamp loads effectively across softer materials or delicate components.
