29N22 - ESAB 29N22 Water Adapter 7/8-14 LH Male to 5/8-18 LH Female

Reliable Water Connections for TIG Welding

The ESAB 29N22 Water Adapter is an essential component for welders utilizing water-cooled TIG torch setups. Designed to facilitate seamless connections between power cables and water lines, this adapter ensures that your cooling system operates efficiently without leaks. Proper cooling is critical for protecting both your torch consumables and the power cable itself during high-amperage welding applications.

Constructed from high-quality brass, this adapter offers excellent durability and resistance to corrosion, which is vital in water-circulation environments. The fitting features a 7/8"-14 Left-Hand (LH) Male thread on one side and a 5/8"-18 Left-Hand (LH) Female thread on the other. The use of left-hand threads is an industry standard for water connections in welding, acting as a safety feature to prevent accidental connection to shielding gas lines (which typically use right-hand threads).

Whether you are setting up a new water cooler or replacing worn-out fittings on an existing rig, the 29N22 adapter provides the precision fit needed for professional results. It is compatible with a wide range of legacy and modern TIG equipment that utilizes standard CGA-style water fittings.

Key Benefits

• Safety First: Left-hand threads prevent dangerous cross-connections with inert gas lines.


• Durable Build: Solid brass construction withstands the rigors of industrial environments.


• Versatile Fit: Bridges the gap between 7/8" power cable nuts and standard 5/8" water hoses.
