Professional Applications & Engineering Value
This Neoprene rubber flat washer is engineered to address critical challenges in industrial assembly, such as component wear from vibration and environmental ingress. The Durometer 55A hardness provides optimal flexibility for sealing and vibration damping, preventing screw back-off and protecting sensitive parts. Its black Neoprene composition resists oils, weathering, and oxidation, making it ideal for electrical enclosures, automotive fittings, and outdoor equipment. With a precise 0.093" ID for No. 2 screws, it ensures easy installation and reliable performance in temperature-fluctuating environments from -20°F to 180°F, enhancing overall assembly integrity and reducing maintenance needs.
Specification Summary & Compliance
This flat washer conforms to inch system dimensions: Inside Diameter 0.093", Outside Diameter 0.188", and Thickness 0.019-0.043". It is manufactured from Neoprene rubber with a Durometer 55A hardness and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring adherence to strict regulations on hazardous substances.
