Professional Applications & Engineering Value

This aluminum metal bonded washer with neoprene seal addresses critical sealing challenges in industrial assemblies where vibration, temperature fluctuations, and environmental exposure compromise ordinary washers. The permanent bond between the aluminum washer and Durometer 65A neoprene rubber creates a reliable barrier against moisture, dust, and mild chemicals while accommodating thermal expansion in equipment operating from -40°F to 250°F. Engineered specifically for 5/16" screw size applications, these washers prevent loosening under dynamic loads and provide consistent compression across the 0.625" OD sealing surface. The black neoprene seal offers excellent UV and ozone resistance, making these metal bonded washers ideal for outdoor equipment, automotive assemblies, and industrial machinery where long-term sealing integrity is paramount.

Specification Summary & Compliance

This precision-engineered washer features exact dimensional specifications with 0.33" inner diameter and 0.625" outer diameter, designed specifically for 5/16" screw applications. The assembly maintains consistent thickness between 0.175-0.210" for uniform compression. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global markets. The neoprene rubber seal maintains Durometer 65A hardness throughout the specified temperature range, providing reliable performance in diverse industrial environments.
