S-92527A110 0.17" ID x 0.496" OD Washdown Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Environmental Protection – Metal-bonded construction with EPDM rubber seals effectively blocks dust, moisture, and liquids, ensuring reliable performance in demanding NEMA 12, 3S, and 4X rated enclosures.
• Excellent Temperature Resilience – Maintains seal integrity across a wide operating range from -30°F to 200°F, suitable for both indoor and outdoor industrial environments.
• Corrosion-Resistant 304 Stainless Steel – Provides long-lasting durability and resistance to rust, ideal for harsh or corrosive settings without compromising structural strength.
• Optimized Seal Hardness (Durometer 60A) – Offers an ideal balance of flexibility and compression set resistance, creating a consistent, long-term seal without over-stressing components.
• Precision Fit for No. 10 Screws – With 0.17" ID and 0.496" OD, ensures easy installation and uniform pressure distribution, reducing the risk of leaks or fastener loosening.
• Full Regulatory Compliance – Meets RoHS 3 and REACH standards, guaranteeing that the washer is free from hazardous substances for safe use in global industrial markets.
• Robust Metal-Rubber Bond – The permanent bond between stainless steel and EPDM prevents seal separation under vibration or thermal cycling, enhancing service life.

Professional Applications & Engineering Value

This 304 stainless steel EPDM sealed washer is engineered to solve critical sealing challenges in industrial enclosures and electrical systems. The metal-bonded design combines the strength of stainless steel with the sealing properties of black EPDM rubber, creating a reliable barrier against contaminants, water, and oils. It is specifically rated for NEMA 12, 3S, and 4X applications, making it ideal for control panels, outdoor machinery, and food processing equipment where environmental ingress protection is mandatory. The Durometer 60A seal material ensures sufficient compression for a tight fit without permanent deformation, while the temperature range from -30°F to 200°F allows deployment in variable climates. By integrating this washer, engineers achieve prolonged enclosure integrity, reduced maintenance, and compliance with industry sealing standards.

Specification Summary & Compliance

The washer features an ID of 0.17", OD of 0.496", and thickness between 0.078-0.126", designed for No. 10 screw size. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements. The EPDM rubber seal with Durometer 60A hardness provides consistent performance, and the assembly is suitable for NEMA 12, 3S, and 4X environmental ratings, confirming its use in dust-tight, oil-resistant, and water-splash conditions.
