Professional Applications & Engineering Value
This neoprene rubber flat washer delivers critical engineering solutions where standard metal washers fall short. The Durometer 55A hardness provides optimal balance between compression set resistance and sealing capability, making it ideal for vibration damping in machinery mounts, electrical enclosures, and automotive assemblies. The black neoprene material maintains elasticity across its -20°F to 180°F temperature range, preventing brittleness in cold environments while resisting deterioration in heated applications. As a sealing washer for No. 8 screws, it creates reliable gasketing surfaces that protect against fluid ingress and environmental contaminants in outdoor equipment, HVAC systems, and industrial controls.
Specification Summary & Compliance
This flat washer maintains precise inch dimensions with 0.312" OD, 0.15" ID, and controlled thickness between 0.047-0.077". Manufactured from neoprene rubber with consistent Durometer 55A hardness, it meets industry standards for compression and recovery. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring unrestricted use in global manufacturing and electronics applications.
