S-94708A516 0.434" ID x 1" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion protection through hot-dipped galvanized steel construction, extending service life in harsh environments
• Reliable environmental sealing with bonded neoprene rubber (Durometer 65A) that maintains flexibility and prevents leakage
• Exceptional temperature resistance from -40°F to 250°F, ensuring consistent performance in extreme thermal conditions
• Optimized load distribution with precise 1" OD and 0.434" ID dimensions for 3/8" fasteners, reducing stress concentrations
• Dual-function design combining metal structural integrity with rubber sealing in a single component, simplifying installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
• Durable metal-rubber bond that withstands vibration and mechanical stress without separation

Professional Applications & Engineering Value

This metal bonded washer addresses critical challenges in industrial sealing applications where both structural support and environmental protection are required. The hot-dipped galvanized steel base provides exceptional corrosion resistance for outdoor equipment, marine applications, and chemical processing facilities, while the permanently bonded neoprene rubber seal (Durometer 65A) creates a reliable barrier against moisture, dust, and contaminants. Engineers specify this 3/8" washer for bolted connections in HVAC systems, agricultural machinery, and transportation equipment where temperature fluctuations from -40°F to 250°F would compromise conventional seals. The integrated design eliminates the need for separate washers and gaskets, reducing assembly time and preventing installation errors in high-volume manufacturing environments.

Specification Summary & Compliance

This metal bonded washer features precise dimensional specifications with 1" OD, 0.434" ID, and thickness ranging 0.086-0.116" for consistent performance with 3/8" fasteners. Manufactured to inch system standards, the component maintains RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for use in regulated industries. The neoprene seal maintains its sealing properties with 65A Durometer hardness throughout the specified temperature range, ensuring reliable performance in demanding industrial applications.
