Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing solutions where standard flat washers fail. The 18-8 stainless steel base provides structural integrity while the chemically bonded neoprene rubber seal creates an impermeable barrier against moisture, dust, and chemicals. Engineered for 5/16" fasteners in industrial equipment, automotive assemblies, and outdoor machinery, these washers solve common challenges of seal degradation under thermal cycling and mechanical stress. The black neoprene seal offers excellent UV and ozone resistance, making these bonded washers ideal for applications requiring both corrosion protection and environmental sealing in temperature extremes from -40°F to 250°F.

Specification Summary & Compliance

Precision manufactured to inch system dimensions with 0.33" inner diameter and 0.875" outer diameter, these metal bonded washers feature a thickness range of 0.169-0.204" for optimal compression. The construction combines 18-8 stainless steel with neoprene rubber seal (Durometer 65A) permanently bonded for reliable performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
