0402 - Western Enterprises 402 Water Y-Connector B-Size LH

Technical Overview of the Western Enterprises 402 Y-Connector

The Western Enterprises 402 is a specialized Y-connector designed for industrial welding coolant systems. Manufactured from high-quality brass, this fitting is engineered to withstand the rigors of daily shop use while resisting corrosion common in water-based cooling loops. The unit features a standard B-Size configuration with 5/8"-18 threads. Crucially, these threads are Left-Hand (LH), a standard safety distinction in the welding industry to prevent the accidental cross-connection of water lines with inert gas or oxygen lines, which typically utilize Right-Hand threads.

This fitting is essential for complex cooling setups where a single coolant source needs to be diverted to multiple components, or conversely, where return lines need to be merged before entering the recirculator. The precision machining of the threads ensures a tight, leak-free seal when used with compatible B-size nuts and nipples. The configuration typically involves a Male connection point branching to Female connections (or adapting thereof), allowing for seamless integration into existing hose assemblies without the need for makeshift adapters that can compromise flow rates or introduce leaks.

In professional MRO environments, maintaining the integrity of the cooling system is paramount to preventing equipment overheating and failure. The Western Enterprises 402 provides a robust solution for extending or modifying hose paths for water-cooled TIG torches, MIG guns, and resistance welding equipment. Its solid brass body offers superior mechanical strength compared to plastic alternatives, ensuring longevity even in high-traffic industrial settings.
