Professional Applications & Engineering Value
This Neoprene rubber flat washer is engineered to address common industrial challenges such as equipment vibration, seal degradation, and thermal expansion. Its Durometer 55A hardness offers ideal compression recovery, preventing seal failure in No. 5 screw fastening systems. The material's innate resistance to oils, weathering, and aging ensures consistent vibration damping and sealing in machinery, electrical enclosures, and automotive components. By maintaining integrity across a temperature range of -20°F to 180°F, it reduces maintenance needs and enhances assembly reliability, making it a critical component for industrial rubber washer applications requiring inch-system compatibility and long-term performance.
Specification Summary & Compliance
This flat washer adheres to inch-system dimensions with an OD of 0.281", ID of 0.141", and thickness range of 0.019-0.043" for precise fit on No. 5 screw sizes. It is manufactured from Neoprene rubber with a Durometer 55A hardness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
