Professional Applications & Engineering Value
This PTFE plastic flat washer solves critical engineering challenges in extreme operating environments where metal washers fail. The chemical-resistant PTFE material maintains integrity when exposed to aggressive solvents, acids, and alkalis that would corrode standard washers. In high-temperature applications up to 500°F, it provides consistent performance where thermal expansion would compromise metal components. The Durometer 55D hardness offers optimal balance between flexibility and structural support, preventing stress cracking under load. For 5/16" screw assemblies in chemical processing, food manufacturing, and electrical enclosures, this washer delivers reliable sealing, insulation, and corrosion protection that extends equipment service life while meeting stringent REACH and RoHS compliance requirements.
Specification Summary & Compliance
Precision-manufactured to inch system dimensions with 0.317" ID and 0.562" OD for exact fit with 5/16" screws. Features controlled thickness variation (0.028-0.036") for consistent performance. Manufactured from virgin PTFE plastic with Durometer 55D hardness rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. Rated for continuous service at 500°F maximum temperature.
