S-94708A138 0.65" ID x 1.25" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel construction, ideal for harsh outdoor and industrial environments
• Reliable sealing performance through permanently bonded neoprene rubber that prevents leakage and ingress of moisture or dust
• Exceptional temperature tolerance from -40°F to 250°F, ensuring consistent performance in extreme thermal conditions
• Optimized load distribution with precise 0.65" ID and 1.25" OD dimensions, reducing surface stress under 5/8" fasteners
• Durable elastomer seal with Durometer 65A hardness, offering excellent compression set resistance and long-term sealing integrity
• Compliance with global standards including RoHS 3 and REACH, meeting strict environmental and safety regulations for industrial use
• Black neoprene seal provides UV resistance and visual contrast for easy inspection during assembly

Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of hot-dipped galvanized steel with the flexibility of a neoprene rubber seal to solve critical sealing challenges in demanding applications. The bonded design eliminates separate gaskets, streamlining assembly while providing a weather-resistant barrier against water, air, and contaminants. Engineers specify these washers for outdoor equipment, HVAC systems, and industrial machinery where thermal cycling from -40°F to 250°F can compromise standard seals. The 5/8" screw size compatibility and inch system measurements ensure easy integration with North American equipment, while the galvanized coating prevents rust in humid or corrosive environments, extending service life and reducing maintenance costs.

Specification Summary & Compliance

This washer features a 0.65" inner diameter and 1.25" outer diameter with a thickness range of 0.173-0.208", designed for 5/8" fasteners. The neoprene seal maintains Durometer 65A hardness for optimal compression. Manufactured to inch system standards, the product is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant with current SVHC declarations, ensuring adherence to environmental and safety regulations for industrial components.
