S-94709A518 0.532" ID x 1" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: Neoprene rubber seal bonded to 18-8 stainless steel prevents leakage and ingress of contaminants in demanding environments.
• Exceptional Temperature Resistance: Operates reliably in extreme conditions from -40°F to 250°F, maintaining seal integrity across thermal cycles.
• Corrosion-Resistant Construction: 18-8 stainless steel core provides excellent resistance to rust and chemical exposure for long-term durability.
• Precision Fit for 1/2" Screws: 0.532" ID ensures secure fastening with standard 1/2" hardware, reducing installation errors.
• Optimized Load Distribution: 1" OD and 0.084-0.114" thickness design spreads pressure evenly, minimizing surface damage.
• Compliant Material Safety: Meets RoHS 3 and REACH standards, ensuring safe use in regulated industrial applications.
• Durable Seal Hardness: Neoprene at Durometer 65A offers ideal flexibility for consistent compression and vibration resistance.

Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the sealing elasticity of neoprene rubber, addressing critical challenges in industrial assembly. The bonded design eliminates separate gaskets, streamlining installation in 1/2" screw applications while providing a reliable barrier against moisture, dust, and mild chemicals. Ideal for outdoor equipment, HVAC systems, and machinery enclosures, it withstands thermal expansion and vibration without compromising the black neoprene seal. Engineers benefit from reduced maintenance cycles and enhanced equipment longevity in temperature-fluctuating environments from -40°F to 250°F.
