Professional Applications & Engineering Value

Our metal bonded washers with neoprene seals deliver critical sealing solutions where standard washers fail. The hot-dipped galvanized steel base provides structural integrity while the permanently bonded neoprene rubber (Durometer 65A) creates an immediate environmental seal against moisture, dust, and contaminants. These industrial washers are engineered for applications requiring reliable performance in temperature-fluctuating environments, from outdoor equipment to mechanical assemblies using No. 8 screws. The black neoprene seal offers excellent UV resistance and visual inspection capability, while the precise 0.18" ID ensures proper fit without compromising installation efficiency. Ideal for electrical enclosures, automotive components, and industrial machinery where both corrosion resistance and environmental sealing are paramount.
