S-94708A412 0.275" ID x 0.75" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion protection with hot-dipped galvanized steel construction, ideal for harsh industrial environments
• Reliable environmental sealing provided by bonded neoprene rubber (Durometer 65A) that maintains flexibility and seal integrity
• Exceptional temperature resilience performing consistently from -40°F to 250°F without compromising seal performance
• Precise dimensional compatibility with 1/4" fasteners (0.275" ID, 0.75" OD) ensuring proper fit and uniform load distribution
• Dual regulatory compliance meeting both RoHS 3 and REACH standards for global industrial applications
• Durable metal-rubber bonding creating a permanent seal that resists separation under vibration and pressure
• Versatile industrial suitability for applications requiring both corrosion resistance and environmental sealing

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 address critical industrial challenges. The bonded design eliminates the need for separate gaskets and washers, providing a unified solution that prevents fluid ingress and corrosion in demanding environments. Engineering teams specify this 1/4 inch washer for applications where thermal cycling, moisture exposure, and chemical resistance are concerns - particularly in outdoor equipment, automotive assemblies, and industrial machinery. The black neoprene seal maintains its sealing properties across extreme temperature fluctuations from -40°F to 250°F, ensuring long-term performance in applications subject to environmental stress and thermal expansion variations.

Specification Summary & Compliance

This inch-system washer features precise dimensions (ID: 0.275", OD: 0.75", Thickness: 0.086-0.116") compatible with 1/4" fasteners. The assembly combines hot-dipped galvanized steel with a neoprene rubber seal rated at Durometer 65A hardness. The product is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
