Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions for applications where conventional washers fail. The PTFE material provides unmatched chemical resistance, making them ideal for chemical processing, pharmaceutical manufacturing, and food processing equipment where exposure to aggressive substances is common. Their 500°F temperature rating ensures reliable performance in high-heat environments such as oven assemblies, thermal processing equipment, and automotive applications. The precise 1" OD and 0.156" ID dimensions specifically engineered for No. 6 screws prevent loosening and distribute load evenly, reducing stress concentrations that lead to fastener failure. The Durometer 55D hardness provides the perfect balance between flexibility and compression resistance, maintaining seal integrity in vibrating machinery and thermal cycling applications where metal washers would corrode or degrade.
