Professional Applications & Engineering Value

This metal bonded washer is engineered to solve critical challenges in industrial sealing and corrosion prevention. The hot-dipped galvanized steel base provides a robust barrier against rust and chemical exposure, while the permanently bonded neoprene rubber seal (Durometer 65A) ensures a reliable, long-lasting seal that resists oils, weather, and aging. Ideal for outdoor equipment, automotive assemblies, and electrical enclosures using No. 8 screw fasteners, this washer maintains seal integrity under vibration and thermal cycling from -40°F to 250°F. Its metal bonded construction prevents seal separation, offering a unified solution that reduces maintenance and replacement costs in demanding industrial applications.
