Professional Applications & Engineering Value

This PTFE plastic flat washer is engineered to solve critical challenges in demanding industrial environments where temperature extremes and chemical exposure compromise standard washers. Its high-temperature rating of 500°F makes it ideal for applications in automotive, aerospace, and chemical processing equipment, where thermal stability is non-negotiable. The inherent chemical resistance of PTFE ensures that the washer will not degrade when exposed to harsh solvents, acids, or bases, maintaining seal integrity and preventing galvanic corrosion. With a Durometer 55D hardness, it provides sufficient crush resistance while accommodating minor surface irregularities, ensuring even pressure distribution for No. 6 screw fastening systems. The low friction coefficient reduces assembly torque and minimizes thread wear, which is crucial for precision equipment and repeated maintenance cycles. By specifying this flat washer, engineers achieve enhanced reliability, reduced downtime, and compliance with stringent industry regulations.
