S-94709A153 0.317" ID x 0.625" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Reliable sealing performance with bonded neoprene rubber that prevents leakage and contamination in demanding applications.
• Broad temperature tolerance from -40°F to 250°F, maintaining seal integrity and mechanical properties under extreme thermal conditions.
• Optimized dimensional fit with 0.317" ID and 0.625" OD designed specifically for 5/16" screws, providing secure fastening and vibration resistance.
• Durable bonded construction where metal and rubber remain securely attached, eliminating separation during installation or use.
• Consistent sealing pressure with Durometer 65A neoprene hardness, offering ideal compression for effective environmental sealing.
• Versatile industrial applicability across machinery, automotive, and outdoor equipment where weatherproofing and chemical resistance are critical.

Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the sealing elasticity of neoprene rubber to solve critical engineering challenges in fluid containment and environmental protection. The bonded design prevents seal displacement under vibration, while the black neoprene material resists oils, weathering, and compression set. Ideal for 5/16" screw applications in pumps, enclosures, and automotive assemblies, it maintains sealing performance across a -40°F to 250°F temperature range, eliminating leaks in thermal cycling conditions. The stainless steel washer provides permanent mounting stability, making it superior to separate gaskets in high-vibration industrial settings.
