Professional Applications & Engineering Value

Engineered for demanding food industry and chemical processing applications, these ePTFE plastic flat washers solve critical sealing and insulation challenges. The expanded PTFE material delivers exceptional stability across extreme temperatures (-400°F to 525°F), eliminating thermal expansion issues that compromise seal integrity. Their FDA compliance directly addresses contamination risks in food processing equipment, while the chemical-resistant properties withstand aggressive sanitizers and industrial fluids. The flat washer design with precise inch dimensions ensures reliable performance under No. 10 screw fastening, providing consistent pressure distribution in high-cycle assembly operations where metal washers would corrode or fail.

Specification Summary & Compliance

This flat washer features inch system dimensions: 0.203" ID, 0.563" OD, and 0.026-0.036" thickness range for No. 10 screw applications. Manufacturing complies with FDA 21 CFR 177.1550 for food contact, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) for chemical safety. The ePTFE plastic construction maintains dimensional stability across the specified temperature range without compromising mechanical properties.
