S-94708A525 0.65" ID x 1.188" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior sealing performance with bonded neoprene rubber that prevents fluid and gas leakage in demanding environments
• Excellent corrosion resistance due to hot-dipped galvanized steel construction, extending service life in harsh conditions
• Wide temperature tolerance from -40°F to 250°F, maintaining seal integrity across extreme thermal cycles
• Optimized compression characteristics with 65A durometer neoprene providing reliable sealing without over-compression
• Precise dimensional fit with 0.65" ID specifically engineered for 5/8" screw applications
• Enhanced load distribution through 1.188" OD design, reducing surface pressure and preventing material damage
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

This metal bonded washer with neoprene seal addresses critical sealing challenges in industrial equipment where environmental factors compromise joint integrity. The hot-dipped galvanized steel base provides structural strength while resisting corrosion in outdoor or chemically aggressive settings. The permanently bonded black neoprene rubber (Durometer 65A) creates a reliable barrier against moisture, dust, and mild chemicals without requiring separate gaskets. Engineers specify this solution for 5/8 inch fastening applications in construction machinery, agricultural equipment, and transportation systems where temperature fluctuations from -40°F to 250°F would degrade conventional seals. The metal-to-rubber bonding technology ensures the seal remains positioned during installation, eliminating misalignment issues common in assembly operations.

Specification Summary & Compliance

This inch-system washer features precise dimensions: 0.65" ID × 1.188" OD with thickness ranging 0.086-0.116". The neoprene rubber seal maintains consistent 65A durometer hardness for predictable compression behavior. Manufacturing complies with industrial standards for metal bonded washers, with full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global supply chains and environmentally conscious manufacturing operations.
