S-94709A211 0.18" ID x 0.5" 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 industrial settings.
• Wide temperature tolerance from -40°F to 250°F, maintaining seal integrity and material properties in extreme thermal conditions.
• Durable, flexible seal with a Durometer 65A neoprene rubber that offers optimal compression and recovery for repeated use.
• Precise dimensional fit with 0.18" ID and 0.5" OD, designed specifically for No. 8 screws to ensure easy installation and secure fastening.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, making them safe for use in regulated industries.
• Reliable performance in varied applications due to the metal-to-rubber bond that resists vibration and prevents seal displacement.

Professional Applications & Engineering Value

This metal bonded washer combines the strength of 18-8 stainless steel with the flexibility of a neoprene rubber seal, offering a robust solution for industrial sealing challenges. The bonded design ensures that the seal remains intact under vibration and pressure fluctuations, preventing leaks in equipment such as pumps, compressors, and electrical enclosures. Its ability to perform in temperatures from -40°F to 250°F makes it ideal for outdoor, automotive, and HVAC systems where thermal cycling is common. The black neoprene seal provides excellent resistance to oils, weather, and aging, while the stainless steel body resists corrosion, reducing maintenance needs and extending service life in corrosive environments.
