S-94709A156 0.531" ID x 1.25" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior sealing performance with permanently bonded neoprene rubber that prevents fluid and gas leakage in demanding environments
• Excellent corrosion resistance provided by 18-8 stainless steel construction, ensuring long-term reliability in harsh conditions
• Wide temperature tolerance from -40°F to 250°F, maintaining seal integrity across extreme thermal cycles
• Optimized compression and durability with a 65A durometer neoprene seal that provides consistent sealing force without premature degradation
• Precise dimensional fit with 0.531" ID and 1.25" OD engineered specifically for 1/2" screw applications
• Enhanced assembly reliability through the metal-to-rubber bond that prevents seal separation during installation and service
• Versatile industrial application capability due to the combination of stainless steel strength and neoprene flexibility

Professional Applications & Engineering Value

These metal bonded washers solve critical sealing challenges in industrial assemblies where vibration, temperature fluctuations, and environmental exposure compromise ordinary washers. The 18-8 stainless steel base provides structural integrity and corrosion resistance, while the permanently bonded black neoprene rubber seal (Durometer 65A) creates a reliable barrier against moisture, dust, and mild chemicals. Engineered for 1/2" screw applications, these washers prevent loosening and maintain consistent sealing pressure in equipment ranging from electrical enclosures and machinery guards to outdoor construction assemblies. The temperature resistance from -40°F to 250°F makes them ideal for applications subject to thermal cycling, eliminating the need for separate gaskets and simplifying assembly processes while ensuring long-term performance in demanding industrial environments.
