S-94708A136 0.4" ID x 1" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel construction, ensuring long-term reliability in harsh industrial environments
• Excellent sealing performance thanks to the bonded neoprene rubber seal that prevents moisture and contaminant ingress
• Wide temperature tolerance from -40°F to 250°F, maintaining seal integrity across extreme thermal conditions
• Optimized dimensional compatibility with 0.4" ID and 1" OD designed specifically for 3/8" screws, ensuring perfect fit and uniform load distribution
• Durable mechanical bond between metal and rubber components that prevents separation under vibration and dynamic loads
• Consistent sealing pressure with 0.173-0.208" thickness range and Durometer 65A neoprene for reliable gasketing performance
• 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 hot-dipped galvanized steel with the sealing reliability of neoprene rubber to solve critical engineering challenges in industrial equipment. The permanent bond between metal and elastomer creates a unified component that withstands vibration-induced loosening while providing consistent environmental sealing. Engineered for 3/8" screw applications, it delivers superior performance in outdoor machinery, HVAC systems, and automotive assemblies where temperature fluctuations from -40°F to 250°F would compromise conventional washers. The black neoprene seal offers excellent resistance to weathering, ozone, and compression set, making it ideal for flange connections, electrical enclosures, and hydraulic systems requiring both mechanical strength and fluid containment.

Specification Summary & Compliance

This heavy-duty washer features precise dimensional specifications with 0.4" inner diameter, 1" outer diameter, and 0.173-0.208" thickness range. The hot-dipped galvanized steel base provides superior corrosion protection, while the bonded neoprene rubber seal (Durometer 65A) ensures reliable gasketing performance. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for industrial components. Designed specifically for use with 3/8" screws, it maintains performance across the specified temperature range of -40°F to 250°F without degradation of sealing properties.
