S-94709A531 0.81" ID x 1.5" 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 environments
• Reliable sealing performance provided by bonded neoprene rubber (Durometer 65A) that maintains flexibility and prevents leakage
• Exceptional temperature tolerance from -40°F to 250°F, ensuring consistent performance across extreme operating conditions
• Precise dimensional compatibility with 0.81" ID and 1.5" OD designed specifically for 3/4" screw applications
• Enhanced vibration resistance through the permanent metal-to-rubber bond that prevents separation under stress
• Regulatory compliance assurance with RoHS 3 and REACH standards for global industrial applications
• Durable black seal that provides both aesthetic consistency and UV resistance in exposed applications

Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing solutions where standard washers fail. The 18-8 stainless steel base provides structural integrity against corrosion and mechanical stress, while the permanently bonded neoprene rubber seal (Durometer 65A) creates an impermeable barrier against moisture, dust, and chemicals. Engineered for industrial applications requiring reliable performance in temperature extremes from -40°F to 250°F, these washers solve common challenges in equipment manufacturing, outdoor machinery, and processing systems where environmental sealing and vibration dampening are essential. The precise 0.81" ID ensures perfect fitment with 3/4" fasteners, eliminating installation issues and reducing maintenance downtime.
