86W40 - B-Size Oxygen Brass Plug with Chain (Right Hand)

Western Enterprises 86W40 Brass Plug & Chain Assembly

The Western Enterprises 86W40 is a precision-engineered brass plug and chain assembly designed for industrial gas equipment maintenance and protection. Manufactured to strict tolerances, this component is essential for preserving the integrity of gas distribution systems, specifically those utilizing B-Size fittings.

Constructed from high-quality brass, the 86W40 offers superior resistance to corrosion and mechanical wear, making it suitable for harsh industrial environments. The plug features a standard 5/8"-18 Right Hand (RH) thread, compliant with CGA connection standards for B-Size outlets typically found on oxygen and inert gas equipment. By securely sealing open outlets on manifolds, regulators, or station drops, this plug effectively prevents the ingress of atmospheric contaminants, moisture, and particulate matter that could otherwise compromise downstream equipment or gas purity.

A key feature of this assembly is the integrated retaining chain. In busy MRO environments, loose protective caps are frequently misplaced. The 86W40 mitigates this risk by physically tethering the plug to the equipment, ensuring it remains accessible for immediate re-application upon disconnection of hoses or downstream devices. This simple yet effective design promotes consistent equipment hygiene and thread protection.
