• Optimized load distribution and vibration dampening from the metal and rubber composite, reducing loosening and component fatigue.
• Easy installation and compatibility with 1/2" screws, featuring precise ID and OD dimensions for a secure, snug fit.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, making it suitable for global industrial supply chains.
• Durable neoprene seal with 65A durometer hardness providing consistent compression set resistance and long-term sealing integrity.

Professional Applications & Engineering Value

This metal bonded washer integrates a hot-dipped galvanized steel base with a neoprene rubber seal to address common industrial challenges such as fluid leakage, thermal expansion, and corrosion. The bonded design ensures that the black neoprene seal remains securely attached during installation and under dynamic loads, offering a reliable barrier against weather elements and chemical exposure. Ideal for industrial applications like HVAC systems, automotive assemblies, and outdoor machinery, this washer maintains sealing performance across a wide temperature range from -40°F to 250°F, preventing failures in fluctuating environments. Its robust construction supports heavy-duty fastening needs, reducing maintenance costs and enhancing operational safety by providing consistent, long-lasting sealing where standard washers may degrade.

Specification Summary & Compliance

This washer features an ID of 0.532", OD of 1.375", and thickness range of 0.179-0.214", designed for use with 1/2" screws in inch system measurements. It adheres to standard dimensional tolerances for precise fit and is manufactured with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it meets environmental and safety regulations for hazardous substances. The neoprene seal material with a durometer hardness of 65A provides optimal compression, while the assembly is suitable for applications requiring reliable performance in varied industrial settings.
