OVERVIEW

Industrial Grade TIG Water Adapter

The ESAB 29N22 is a precision-engineered water adapter designed to meet the demands of professional fabricators and industrial welding operations. This fitting is specifically manufactured to adapt water-cooled TIG torch power cables to standard water supply hoses or cooler connections. By converting a 7/8"-14 LH Male thread to a 5/8"-18 LH Female thread, it solves common compatibility issues found when integrating torches from different manufacturers or generations.

In heavy-duty TIG welding, maintaining a consistent flow of coolant is non-negotiable. A leak in the system can lead to torch overheating, cable failure, and costly downtime. The ESAB 29N22 is machined to tight tolerances to ensure a secure, leak-proof seal when tightened properly. The brass material provides superior mechanical strength and resistance to oxidation, ensuring a long service life even with continuous exposure to coolant fluids.

This adapter is commonly used with Heliarc style torches and other major brands that adhere to traditional water-cooling connection standards. It is an indispensable part of any maintenance repair and operations (MRO) inventory for shops running water-cooled GTAW equipment.

FAQ

The adapter features a 7/8"-14 Left-Hand Male thread on one end and a 5/8"-18 Left-Hand Female thread on the other.

Left-hand threads are the industry standard for water and fuel gas connections to prevent accidental cross-connection with shielding gas (Argon/Oxygen) lines, which use right-hand threads.

It is machined from solid brass, providing durability and corrosion resistance for water applications.

No, this adapter is designed for water connections. Gas connections typically require right-hand threads.

It is compatible with torches and cables that utilize the specific 7/8-14 and 5/8-18 LH thread standards, common in many industrial water-cooled setups.

While brass fittings often seal metal-to-metal or via a seated gland, using a small amount of appropriate thread sealant or tape can ensure a leak-free seal, provided it doesn't block the flow path.

Its primary function is to adapt the large nut on a water-cooled power cable to a standard size water hose.

Yes, the SKU ESB29N22 corresponds to the genuine ESAB (formerly Linde/L-Tec) part number 29N22.
