S-94709A132 0.532" ID x 1.062" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: Neoprene rubber seal bonded to 18-8 stainless steel prevents leaks and protects against moisture, dust, and contaminants in demanding environments.
• Wide Temperature Resilience: Maintains sealing integrity across an extensive operating range from -40°F to 250°F, suitable for both extreme cold and moderate heat applications.
• Durable Corrosion Resistance: 18-8 stainless steel construction provides excellent resistance to rust and corrosion, extending service life in harsh industrial settings.
• Precise Fit for 1/2" Fasteners: 0.532" ID ensures secure and accurate seating on 1/2" screws, reducing installation errors and improving assembly reliability.
• Optimal Seal Hardness: Durometer 65A Neoprene offers ideal compression and recovery, creating a long-lasting, vibration-resistant seal without over-stressing components.
• Environmental Regulation Compliance: Meets RoHS 3 and REACH standards, ensuring safe use in regulated industries and global market acceptance.
• Robust Mechanical Design: Metal-to-rubber bonded construction prevents seal separation under pressure, providing consistent performance in high-vibration applications.

Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the flexibility of a Neoprene rubber seal to solve critical sealing challenges in industrial equipment, machinery, and outdoor installations. The bonded design eliminates the risk of seal displacement during assembly or operation, ensuring reliable protection against fluid ingress and environmental exposure. Engineers specify this component for pump housings, valve covers, electrical enclosures, and automotive assemblies where temperature fluctuations from -40°F to 250°F could compromise standard seals. The black Neoprene seal offers excellent resistance to oils, weathering, and compression set, while the stainless steel washer distributes clamp load evenly to prevent gasket blow-out. This integrated solution reduces maintenance frequency and prevents costly downtime in industrial washers applications requiring consistent pressure retention.

Specification Summary & Compliance
