S-94708A124 0.434" ID x 0.81" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel construction, ideal for harsh industrial environments
• Reliable sealing performance due to permanently bonded neoprene rubber seal that prevents leakage and contamination
• Wide temperature tolerance from -40°F to 250°F, ensuring consistent performance in extreme operating conditions
• Optimized dimensional fit with 0.434" ID and 0.81" OD designed specifically for 3/8" screw applications
• Durable seal integrity maintained by 65A durometer neoprene, balancing flexibility and compression resistance
• Regulatory compliance assurance with RoHS 3 and REACH adherence for global industrial supply chain compatibility
• Enhanced service life through the combination of robust steel carrier and weather-resistant rubber seal

Professional Applications & Engineering Value

This metal bonded washer solves critical sealing challenges in industrial equipment, outdoor structures, and mechanical assemblies where environmental protection is paramount. The hot-dipped galvanized steel body provides sacrificial corrosion protection while the permanently bonded neoprene seal (Durometer 65A) maintains compression set resistance under varying pressures. Engineers specify this 3/8" washer for applications requiring reliable weather sealing in HVAC systems, agricultural machinery, and transportation equipment where temperature fluctuations (-40°F to 250°F) and moisture exposure would compromise standard washers. The black neoprene formulation offers UV resistance and visual contrast for installation quality control.

Specification Summary & Compliance

Manufactured to inch system standards with precise dimensions: 0.434" ID × 0.81" OD × 0.181-0.216" thickness. The metal bonded construction ensures permanent seal retention without separation during installation. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances per the latest SVHC list (updated 06/14/2023). The neoprene rubber seal maintains performance within specified temperature ranges while the hot-dipped galvanized surface treatment provides consistent corrosion protection.
