• Optimized compression and vibration resistance with the 65A durometer neoprene providing ideal flexibility and sealing force
• Precise dimensional compatibility with 0.625" OD and 0.4" ID ensuring perfect fit for 3/8" screw applications
• Enhanced durability in demanding applications through the metal-to-rubber bonded construction that prevents separation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This metal bonded washer combines the structural integrity of 18-8 stainless steel with the sealing performance of neoprene rubber to solve critical engineering challenges in industrial equipment. The permanent bond between metal and rubber eliminates gasket separation issues common in high-vibration environments, while the black neoprene seal (Durometer 65A) provides optimal compression for preventing fluid and gas leakage. Engineered for 3/8" screw applications, this washer delivers reliable performance in automotive assemblies, machinery enclosures, and outdoor equipment where temperature fluctuations from -40°F to 250°F would compromise ordinary seals. The precise 0.625" OD and 0.4" ID dimensions ensure proper seating and uniform pressure distribution, making it an essential component for maintenance professionals seeking to enhance equipment reliability and reduce downtime.

Specification Summary & Compliance

This metal bonded washer features inch system dimensions with 0.625" outer diameter, 0.4" inner diameter, and thickness ranging from 0.169" to 0.204" specifically designed for 3/8" screw size applications. Manufactured from 18-8 stainless steel with a bonded neoprene rubber seal rated at Durometer 65A hardness, the product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial markets worldwide.
