Professional Applications & Engineering Value

This metal bonded washer combines the strength of 18-8 stainless steel with the flexibility of a neoprene rubber seal to solve critical sealing challenges in industrial applications. The bonded design eliminates gaps that cause fluid or gas leaks, while the black neoprene seal (Durometer 65A) maintains elasticity across a wide temperature range from -40°F to 250°F. Engineers value its ability to withstand corrosive environments, vibrations, and pressure variations in machinery, piping systems, and outdoor equipment. Its precise 0.81" ID and 1.75" OD dimensions ensure a secure fit for 7/8" screw applications, reducing installation time and preventing assembly failures in automotive, construction, and marine sectors.

Specification Summary & Compliance

This washer features an inner diameter of 0.81", outer diameter of 1.75", and thickness between 0.164" and 0.199", designed for use with 7/8" screws in inch-based systems. The 18-8 stainless steel body offers inherent corrosion resistance, while the neoprene seal provides a Durometer 65A hardness for optimal compression. It fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to hazardous substance restrictions and environmental safety standards for industrial components.
