10N18 - 10N18 TIG Power Cable Hose Nut, 7/8-14 LH

Precision Brass Connection for TIG Assemblies

The 10N18 Hose Nut is a critical hardware component designed for the assembly and maintenance of TIG welding torch systems. Manufactured from high-quality brass, this nut is engineered to withstand the thermal cycling and mechanical stresses common in industrial welding environments. Its primary function is to secure power cables, water hoses, or gas lines to power cable adapters (such as the 45V series) used with air-cooled and water-cooled TIG torches.

The specific thread configuration of this nut is 7/8"-14 Left Hand (LH). The use of left-hand threads is a standard safety and organizational feature in welding gas and water systems, distinguishing these connections from standard right-hand thread compressed gas fittings. This prevents accidental cross-connection of incompatible lines, ensuring that water or specific shielding gases are routed correctly through the torch body. The 0.88-inch (approx. 7/8") diameter provides a robust mating surface, ensuring a tight seal that prevents leaks which could compromise weld quality or cooling efficiency.

This component is compatible with a wide range of industry-standard TIG torches, including the 17, 18, and 26 series, as well as various water-cooled setups. It is an essential spare part for maintenance, repair, and operations (MRO) inventories, allowing for quick replacement of stripped, lost, or damaged nuts during torch reassembly. Proper installation of the 10N18 nut ensures electrical continuity in power cables and fluid integrity in cooling lines, contributing to the overall reliability of the welding station.
