Professional Applications & Engineering Value

This clear polyurethane rubber flat washer delivers critical engineering solutions where standard metal washers fall short. Its Durometer 70A hardness provides the perfect balance between flexibility and load distribution, preventing surface damage while maintaining seal integrity in industrial equipment, electrical enclosures, and machinery assemblies. The temperature-resistant polyurethane material maintains performance across extreme conditions from -10°F to 150°F, solving common issues with material brittleness or deformation. The precise 0.656" ID ensures perfect fitment for 5/8" screw applications while the 1.75" OD provides optimal surface coverage. These inch system washers are particularly valuable in applications requiring chemical resistance, electrical insulation, and corrosion prevention where metal components would degrade.
