Professional Applications & Engineering Value

This metal bonded washer combines the structural integrity of hot-dipped galvanized steel with the sealing reliability of neoprene rubber to address critical challenges in industrial assembly. The permanent bond between metal and seal creates an impermeable barrier against environmental factors, making it ideal for outdoor equipment, marine applications, and HVAC systems where moisture resistance is paramount. The black neoprene seal with Durometer 65A hardness ensures consistent compression without permanent deformation, while the temperature resistance from -40°F to 250°F guarantees performance stability across seasonal variations. Engineered for 7/8" screw size applications, this washer provides both corrosion protection and environmental sealing in a single component, reducing installation time and improving long-term reliability in demanding industrial settings.

Specification Summary & Compliance

This heavy-duty washer features precise dimensional specifications with 0.91" inner diameter and 1.75" outer diameter, designed specifically for 7/8" screw applications. The construction utilizes hot-dipped galvanized steel for superior corrosion resistance permanently bonded to a neoprene rubber seal rated at Durometer 65A hardness. The assembly demonstrates full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental responsibility and material safety. The temperature performance range of -40°F to 250°F makes it suitable for various industrial environments while maintaining sealing integrity and structural performance.
