0004401401 - ESAB Double Hose Splicer LW 6 (6mm) Brass Connector

Reliable Connection for Industrial Welding Systems

The ESAB Double Hose Nipple LW 6 (Part Number: 0004401401) is a critical component for maintaining the integrity of fluid and gas delivery systems in professional welding environments. Designed with precision engineering, this brass fitting is specifically calibrated for hoses with a nominal internal width of 6mm (LW 6). In industrial settings where equipment downtime equates to lost revenue, utilizing genuine OEM parts like this hose nipple ensures compatibility and reliability that generic fittings often fail to match.

Constructed from high-grade brass, this double nipple offers superior resistance to corrosion and mechanical wear. This is particularly important in welding applications where cooling water lines and shielding gas hoses are subjected to fluctuating pressures and harsh workshop conditions. The brass material ensures that the threads or barbs maintain their geometry over time, preventing leaks that could compromise weld quality (in the case of shielding gas) or torch integrity (in the case of water cooling).

The "Double Hose Nipple" designation typically refers to a connector designed to join two lengths of hose or to interface a hose with a machine port, depending on the specific configuration of the ESAB equipment it is intended for. Its LW 6 sizing is a standard metric specification found on many European-designed welding machines and torch assemblies. Proper installation of this nipple guarantees a tight seal, minimizing the risk of atmospheric contamination in gas lines—a common cause of porosity in MIG and TIG welding.

For maintenance, repair, and operations (MRO) professionals, stocking essential fittings like the ESAB 0004401401 is a proactive measure. Whether repairing a severed line or extending the reach of a welding station, this component provides a quick and secure solution. It is compatible with standard hose clamps (crimped or worm-drive), allowing for versatile installation options based on the specific pressure requirements of the system.
