Professional Applications & Engineering Value

This metal bonded washer combines the structural integrity of 18-8 stainless steel with the sealing properties of black neoprene rubber to solve critical engineering challenges in industrial applications. The permanent bonding between metal and rubber eliminates gasket misalignment and separation issues common in traditional sealing methods. Engineered for 3/8" screw applications, this washer provides reliable fluid and environmental sealing in automotive assemblies, electrical enclosures, and outdoor equipment where temperature fluctuations from -40°F to 250°F would compromise ordinary seals. The Durometer 65A hardness of the neoprene seal ensures optimal compression while maintaining flexibility, making it ideal for vibration-prone environments where consistent sealing performance is critical to operational safety and equipment longevity.

Specification Summary & Compliance

This precision metal bonded washer features exact dimensional specifications with 0.434" inner diameter and 1.25" outer diameter, designed specifically for 3/8" screw applications in inch measurement systems. The component maintains strict manufacturing consistency with thickness ranging between 0.175-0.210". The product fully complies with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental responsibility and workplace safety. The combination of 18-8 stainless steel and neoprene rubber seal with Durometer 65A hardness provides a robust sealing solution suitable for industrial applications requiring reliable performance across diverse operating conditions.
