S-94709A144 0.203" ID x 0.406" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: The permanently bonded neoprene rubber seal provides a reliable, leak-proof barrier against moisture, dust, and contaminants, enhancing assembly integrity.
• Excellent Corrosion Resistance: Made from 18-8 Stainless Steel, this washer offers long-lasting durability and resistance to rust in harsh environments.
• Wide Temperature Tolerance: With a functional range from -40°F to 250°F, it maintains performance and seal elasticity in both extreme cold and moderate heat.
• Optimized Fit and Vibration Dampening: Precisely engineered for a No. 10 screw (0.203" ID), it ensures a snug fit and the Durometer 65A seal absorbs shock and reduces loosening.
• Dual-Material Durability: The metal-rubber bond combines the structural strength of stainless steel with the flexible, compressive seal of neoprene for long-term reliability.
• Easy Identification and Aesthetics: The black neoprene seal allows for quick visual inspection and provides a clean, professional finish.

Professional Applications & Engineering Value

This metal bonded washer is engineered to solve critical challenges in industrial assembly and maintenance. The core value lies in its 18-8 stainless steel body, which provides structural integrity and corrosion resistance, paired with a neoprene rubber seal that acts as a permanent gasket. This design is ideal for applications requiring a sealed joint, such as in electrical enclosures, outdoor machinery, automotive components, and plumbing fixtures, where preventing fluid ingress and compensating for surface irregularities is paramount. The inch system dimensions ensure compatibility with standard No. 10 screw fasteners, making it a reliable, off-the-shelf solution for engineers seeking to enhance the longevity and environmental sealing of their products without custom parts.

Specification Summary & Compliance

This washer conforms to standard inch system measurements with an Inside Diameter (ID) of 0.203", Outside Diameter (OD) of 0.406", and a Thickness of 0.096-0.115". It is manufactured for use with No. 10 screw sizes. The seal material is specified as Neoprene Rubber with a hardness of Durometer 65A. Components are designed and produced following industry best practices for bonded seal washers and are generally compliant with RoHS and REACH environmental directives, ensuring they are free from hazardous substances for use in various global markets.
