• Versatile industrial suitability with black neoprene seal providing consistent performance across various applications

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these metal bonded washers combine the structural strength of hot-dipped galvanized steel with the sealing reliability of neoprene rubber to solve critical engineering challenges. The permanent bond between metal and rubber prevents component separation that commonly occurs in high-vibration environments, while the Durometer 65A seal hardness provides optimal compression and recovery for long-term sealing integrity. Ideal for outdoor equipment, automotive assemblies, and industrial machinery requiring corrosion resistant washers, this solution addresses the dual need for mechanical strength and environmental protection. The temperature resistant design ensures consistent performance from arctic conditions to elevated thermal environments, making these sealing washers essential for applications where both structural integrity and environmental sealing are paramount.
