Professional Applications & Engineering Value
Engineered for demanding industrial environments, these PTFE plastic flat washers solve critical challenges in chemical processing, food manufacturing, and high-temperature applications. The white PTFE material provides inherent chemical resistance against aggressive solvents, acids, and bases, while maintaining structural integrity at continuous temperatures up to 500°F. The flat washer design with precise 0.39" ID and 1.75" OD dimensions ensures proper load distribution and prevents galvanic corrosion when used with dissimilar metals. These characteristics make them ideal for 3/8" screw applications in plating facilities, semiconductor manufacturing, and pharmaceutical equipment where contamination prevention and thermal stability are paramount.
Specification Summary & Compliance
This flat washer features inch system measurements with 0.39" inner diameter and 1.75" outer diameter, specifically designed for 3/8" screw size applications. The PTFE plastic construction maintains dimensional stability with a thickness range of 0.057-0.067" and Durometer 55D hardness. Manufacturing complies with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory acceptance for international industrial applications.
