Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions where chemical exposure and extreme temperatures compromise conventional fasteners. The white PTFE material provides inherent resistance to corrosive chemicals, solvents, and aggressive industrial fluids, eliminating galvanic corrosion concerns in mixed-material assemblies. With a maximum temperature rating of 500°F, these washers maintain dimensional stability in high-heat applications including automotive, chemical processing, and food equipment. The 0.188" ID precisely accommodates No. 8 screws while the 0.375" OD ensures adequate load distribution on softer materials. Their non-conductive properties make them ideal for electrical insulation applications, providing both mechanical fastening and electrical safety in compact assemblies.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with 0.188" inner diameter and 0.375" outer diameter, these flat washers maintain consistent thickness between 0.036-0.045" for reliable performance. The PTFE material achieves Durometer 55D hardness for optimal mechanical properties. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to international environmental and safety standards for industrial components.
