- Consistent dimensional stability with precise 0.531" ID and 2" OD for perfect fit with 1/2" fasteners
- Optimal load distribution with controlled 0.027-0.035" thickness and Durometer 55D hardness for even pressure spreading
- Full regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries
- Excellent electrical insulation properties providing reliable isolation in electrical applications
Professional Applications & Engineering Value
This PTFE plastic flat washer delivers critical engineering solutions where conventional washers fail. The PTFE material provides exceptional chemical resistance against aggressive solvents, acids, and bases, while maintaining structural integrity at continuous temperatures up to 500°F. The non-stick properties prevent seizing and binding with mating surfaces, eliminating galling issues common in metal fasteners. With precise 1/2" screw size compatibility and consistent 2" OD dimensions, these washers ensure proper load distribution in chemical processing equipment, high-temperature machinery, food processing systems, and electrical enclosures where corrosion resistance and thermal stability are paramount.
Specification Summary & Compliance
This flat washer meets inch system specifications with 0.531" ID, 2" OD, and 0.027-0.035" thickness tolerance. The PTFE material achieves Durometer 55D hardness for optimal performance balance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The white color provides visual identification for quality control in assembly operations.
