Professional Applications & Engineering Value

This No. 6 metal bonded washer is engineered to address critical sealing challenges in industrial equipment, such as hydraulic systems, compressors, and automotive assemblies. The zinc-plated steel core provides structural strength and corrosion resistance, while the bonded Buna-N rubber seal (with a black color for easy identification) ensures a tight seal against fluids and gases. Its ability to withstand temperatures from -40°F to 225°F and extreme pressures up to 10,800 PSI for fluids makes it ideal for applications where failure is not an option, reducing maintenance downtime and enhancing operational safety. By integrating this washer, engineers achieve reliable leak prevention and long-term durability in harsh environments.

Specification Summary & Compliance

The washer features precise dimensions with an ID of 0.13", OD of 0.385", and thickness of 0.036-0.044", designed for No. 6 screw sizes. It meets industry standards for material hardness (Rockwell B71 for steel and Durometer 55A for the Buna-N seal) and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
