Professional Applications & Engineering Value

This PVC plastic flat washer is engineered to solve critical challenges in industrial and chemical settings where metal washers fail. Its gray PVC material offers inherent resistance to a wide range of chemicals, acids, and alkalis, preventing degradation and extending service life in aggressive environments. The washer provides essential electrical insulation, making it a safe choice for electrical enclosures and control panels to avoid conductivity issues. With a Durometer 65D hardness, it maintains structural integrity under compression, distributing load evenly to protect surfaces and prevent loosening from vibrations. Designed for 1/4" screw applications in the inch system, it ensures a precise fit, reducing installation time and improving assembly reliability in plumbing, HVAC, and food processing equipment where non-metallic, RoHS and REACH compliant components are mandated.
