S-94708A414 0.434" ID x 0.75" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion protection with hot-dipped galvanized steel construction, ensuring long-term durability in harsh industrial environments
• Reliable fluid and dust sealing thanks to the permanently bonded neoprene rubber seal that prevents leakage and contamination
• Excellent temperature resilience maintaining performance across a wide range from -40°F to 250°F for versatile application use
• Optimized compression and grip with precise 0.434" ID and 0.75" OD dimensions ensuring perfect fit for 3/8" fasteners
• Consistent sealing performance with 65A durometer neoprene providing ideal flexibility and compression recovery
• Enhanced safety compliance meeting RoHS 3 and REACH environmental standards for regulated industries
• Durable metal-rubber bond creating a permanent seal that won't separate under vibration or pressure changes

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 demanding environments. The permanent bond between metal and sealant prevents the common failure point of separate washers and gaskets, providing a unified solution that maintains integrity under vibration and thermal cycling. Ideal for industrial applications requiring both corrosion resistance and environmental sealing, this washer effectively protects against moisture, dust, and chemical ingress in outdoor equipment, automotive assemblies, and machinery enclosures. The black neoprene seal with 65A durometer hardness offers optimal compression set resistance, ensuring long-term sealing performance while the galvanized coating provides sacrificial protection against rust and degradation.
