10Z30 - ESAB 10Z30 TIG Water Adapter 5/8-18 LH to 1/4 NPT

Technical Overview of the ESAB 10Z30 Water Adapter

The ESAB 10Z30 Water Adapter is a critical component for industrial TIG welding setups requiring liquid cooling. Designed to interface between standard water-cooled torch hoses and water supply equipment, this adapter features a specific thread configuration to ensure safety and compatibility. The unit converts a standard 5/8"-18 Left Hand (LH) female thread—commonly found on "B-size" water hoses—to a 1/4" NPT Male thread, which is the industry standard for ports on water coolers, recirculators, and solenoid valves.

Manufactured from high-quality brass, the 10Z30 offers excellent resistance to corrosion and oxidation, essential for components in constant contact with water or coolant mixtures. The precision-machined threads ensure a tight mechanical seal, preventing coolant leaks that could compromise weld quality or damage equipment. This part is a direct replacement for legacy L-Tec and Heliarc water adapters and is compatible with a wide range of water-cooled TIG torches.
