Professional Applications & Engineering Value

Engineered for demanding environments where conventional washers fail, these PTFE flat washers deliver critical performance advantages. The white PTFE material offers near-universal chemical resistance, eliminating contamination risks in pharmaceutical, food processing, and semiconductor equipment. With a maximum temperature rating of 500°F, they maintain structural integrity in thermal cycling applications from automotive engine compartments to industrial ovens. The metric M3.5 compatibility and precise dimensional tolerances ensure secure fastening in precision instruments and electronic enclosures, while the low coefficient of friction prevents thread damage during repeated assembly operations. These plastic washers solve electrical insulation challenges while providing reliable sealing in corrosive fluid handling systems.

Specification Summary & Compliance

Manufactured to precise metric standards with 3.7mm inner diameter and 8mm outer diameter dimensions, these flat washers maintain consistent 0.6-0.9mm thickness across the production batch. The PTFE material achieves Durometer 51D hardness for optimal mechanical properties. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
