• Enhanced vibration resistance through the metal-to-rubber bonded design, preventing loosening under dynamic loads
• Precision fit for 3/8" screws with 0.434" ID and 1" OD dimensions, ensuring proper installation and load distribution
• Consistent sealing performance with Durometer 65A neoprene providing optimal compression and recovery characteristics
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the sealing elasticity of neoprene rubber to solve critical engineering challenges in industrial equipment. The permanent bond between metal and rubber creates a reliable barrier against environmental contaminants while providing vibration damping - essential for machinery, automotive, and outdoor applications where thermal cycling from -40°F to 250°F would compromise conventional seals. The black neoprene seal maintains consistent compression across temperature extremes, preventing fluid leakage and protecting threaded fasteners from corrosion. This industrial washer delivers dual functionality as both a load-bearing surface and environmental seal, eliminating the need for separate components in 3/8" screw applications requiring both mechanical stability and protected assemblies.
