Professional Applications & Engineering Value

This PVC plastic flat washer delivers critical engineering solutions where metal components fail. The gray PVC material provides inherent chemical resistance against acids, alkalis, and industrial solvents, making it ideal for chemical processing equipment, water treatment facilities, and laboratory applications. Its excellent electrical insulation properties prevent galvanic corrosion and current leakage in electrical enclosures, control panels, and marine installations. The precise 0.656" ID ensures secure seating on 5/8" screws while the generous 2.25" OD distributes load effectively across softer materials. These industrial washers maintain dimensional stability in varying temperatures, offering reliable performance in plumbing, HVAC, and food processing equipment where corrosion resistance and electrical isolation are paramount.
