S-94709A133 0.532" ID x 1.375" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Excellent sealing capability through permanently bonded neoprene rubber that prevents fluid and gas leakage
• Wide temperature tolerance from -40°F to 250°F for reliable operation in extreme thermal conditions
• Precise dimensional compatibility with 0.532" ID and 1.375" OD ensuring perfect fit for 1/2" screw applications
• Optimized seal performance with 65A durometer neoprene providing ideal compression and recovery characteristics
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
• Dual-material durability combining stainless steel structural integrity with neoprene's sealing flexibility

Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing solutions where standard washers fail. The 18-8 stainless steel base provides structural stability while the permanently bonded neoprene rubber seal (Durometer 65A) creates an impermeable barrier against moisture, dust, and chemicals. Engineered for 1/2" screw applications, these washers solve common industrial challenges in equipment manufacturing, plumbing systems, and outdoor machinery where thermal cycling from -40°F to 250°F would compromise ordinary seals. The black neoprene composition maintains flexibility across this temperature range while the stainless steel prevents galvanic corrosion, making them ideal for marine, chemical processing, and food equipment applications requiring reliable, long-term sealing performance.

Specification Summary & Compliance

Precision-engineered with 0.532" inner diameter and 1.375" outer diameter with thickness ranging 0.175-0.210" for optimal compression. Manufactured to exacting standards for 1/2" screw compatibility, these metal bonded washers feature a neoprene rubber seal rated at Durometer 65A hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The construction combines 18-8 stainless steel's corrosion resistance with neoprene's sealing properties for industrial-grade performance across diverse applications.
