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

Get Your TIG Torch Back in Action

There is nothing more frustrating than a stripped thread or a missing nut halting your fabrication project. The 10N18 Hose Nut is the exact replacement part you need to secure your TIG power cable adapter or water hose connection. If you are running a standard TIG setup—whether it is an air-cooled WP-26 or a water-cooled WP-18—chances are your rig relies on this specific nut to keep everything connected and flowing smoothly.

Why the Left-Hand Thread?
You will notice this nut tightens to the left (counter-clockwise). This 7/8"-14 LH thread is designed that way on purpose. In the welding world, left-hand threads often signify fuel or water connections to keep you from accidentally hooking up the wrong line to the wrong port. This nut ensures that your power cable adapter locks in securely without the risk of mixing up your connections. It is made from solid brass, so it won't rust out from water exposure and it stands up to the daily grind of the shop.

Quick Fix for Common Issues
Over time, threads can get crossed, flats can get rounded off by pliers, or parts just get lost during a tear-down. Keeping a few 10N18 nuts in your toolbox means you are never stuck waiting on a small hardware part while a job sits unfinished. It fits standard power cable adapters and provides that snug, leak-free fit you need to maintain consistent gas coverage and cooling. Don't let a loose connection ruin your arc stability—swap in a fresh 10N18 and get back to laying dimes.
