S-94708A132 0.275" ID x 0.735" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: Neoprene rubber seal (Durometer 65A) ensures a tight, reliable seal against moisture, dust, and contaminants in demanding environments.
• Exceptional Corrosion Resistance: Hot-Dipped Galvanized Steel construction provides a robust barrier against rust and degradation, extending service life in harsh conditions.
• Wide Temperature Tolerance: Withstands extreme temperatures from -40°F to 250°F, making it suitable for both freezing and high-heat industrial applications.
• Durable Metal Bonded Design: The permanent bond between the steel washer and neoprene seal prevents separation under vibration and pressure, ensuring long-term integrity.
• Precision Fit for 1/4" Screws: With an ID of 0.275" and OD of 0.735", it offers a secure and accurate fit, reducing installation errors and improving assembly efficiency.
• Environmental & Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring safety for use in regulated industries and promoting eco-friendly manufacturing.
• Versatile Industrial Application: Ideal for machinery, automotive, and outdoor equipment where reliable sealing and corrosion protection are critical.

Professional Applications & Engineering Value

This metal bonded washer is engineered to address common industrial challenges such as fluid leakage, corrosion-induced failure, and seal degradation under thermal stress. The hot-dipped galvanized steel body offers excellent durability and corrosion resistance, while the bonded neoprene rubber seal (Durometer 65A) maintains flexibility and sealing integrity across a broad temperature range from -40°F to 250°F. It is particularly valuable in applications like heavy machinery, automotive assemblies, and electrical enclosures, where it prevents ingress of water, oils, and debris. By combining a robust metal base with an elastic seal, this washer reduces maintenance needs and enhances the reliability of industrial fastening systems, supporting long-term operational safety and efficiency.

Specification Summary & Compliance
