Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions for demanding industrial applications where conventional washers fail. The chemical-resistant properties of PTFE material make these washers ideal for chemical processing, pharmaceutical manufacturing, and food processing equipment where exposure to aggressive substances is common. The high-temperature capability up to 500°F ensures reliable performance in thermal cycling applications, automotive systems, and industrial machinery subject to heat stress. The 0.39" ID and 0.875" OD dimensions provide precise fitment for 3/8" fasteners in inch system assemblies, while the controlled thickness maintains proper clamping force without material deformation. These washers serve as essential components in applications requiring non-conductive, low-friction properties combined with regulatory compliance for global industrial standards.
