S-94708A129 0.2" ID x 0.5" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior sealing performance with bonded neoprene rubber that prevents leakage and protects against dust, moisture, and contaminants in industrial environments.
• Excellent corrosion resistance due to the hot-dipped galvanized steel construction, ensuring long-term durability even in harsh conditions.
• Wide temperature tolerance from -40°F to 250°F, making it reliable for applications exposed to extreme thermal variations.
• Secure and vibration-resistant fit with precision dimensions (0.2" ID, 0.5" OD) designed specifically for No. 10 screws, reducing loosening over time.
• Enhanced grip and cushioning from the Durometer 65A neoprene seal, which absorbs shock and distributes load evenly to prevent surface damage.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global industrial supply chains.
• Durable metal-rubber bond that maintains integrity under pressure, offering consistent performance in heavy-duty assemblies.

Professional Applications & Engineering Value

This metal bonded washer combines a hot-dipped galvanized steel body with a neoprene rubber seal to address common industrial challenges like fluid ingress, vibration loosening, and corrosion. The black neoprene seal (Durometer 65A) provides a tight, flexible barrier ideal for outdoor equipment, automotive assemblies, and machinery exposed to temperature swings from -40°F to 250°F. Its inch system measurements and precise inner diameter for No. 10 screws ensure easy integration into existing designs, reducing installation errors and enhancing the longevity of fastened joints. By offering reliable sealing and corrosion resistance, this washer minimizes maintenance needs and boosts operational reliability in demanding settings.

Specification Summary & Compliance

This washer features an ID of 0.2", OD of 0.5", and thickness range of 0.176-0.211", tailored for No. 10 screw size in inch-based systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious industrial applications. The hot-dipped galvanized steel and neoprene seal materials ensure consistent performance across specified temperature limits, supporting adherence to common industry standards for reliability and safety.
