11N18 - Weldcraft 11N18 Water Hose Coupler 5/8-18 LH Brass

Extend Your Reach with the Weldcraft 11N18 Water Coupler

For professional TIG welders utilizing water-cooled setups, the Weldcraft 11N18 Water Hose Coupler is a small but indispensable tool in your kit. When you are working on large projects or in tight spaces where your standard torch leads just aren't long enough, extending your lines becomes necessary. This brass coupler allows you to seamlessly connect water coolant hoses, giving you the extra length needed to reach your work without moving your entire machine and cooler setup. Designed specifically for the rigors of the welding shop, it ensures that your torch stays cool, no matter how far you are from the base unit.

The 11N18 features industry-standard 5/8"-18 LH (Left Hand) threads. If you have ever struggled with fittings, you know the importance of the left-hand thread convention in welding—it ensures you never accidentally plug your water line into your argon outlet. This coupler connects Inert LH Female threads to B-Size LH Female threads, making it the perfect bridge for extending standard TIG water coolant hoses. It is specifically listed for use with Weldcraft CS310 and CS410 torches, but its standard sizing makes it a versatile problem-solver for various water-cooled applications requiring B-size connections.

Made from durable brass, this coupler stands up to the rough handling of a busy shop floor and resists corrosion from water and coolant additives. A solid, leak-proof connection is non-negotiable when dealing with water-cooled torches; a leak not only makes a mess but can drop coolant pressure, causing your expensive torch head to overheat and burn out in seconds. With the Weldcraft 11N18, you get a secure, tight seal that maintains proper flow rates to the head.

Whether you are building a custom cable assembly, repairing a damaged line, or simply need to add an extension for a specific job, this coupler is the right part for the task. Keep a few 11N18 couplers in your toolbox or parts bin so you are never stuck with a hose that's just a few feet too short. Trust in genuine Miller Weldcraft components to keep your equipment running at peak performance, letting you focus on laying down the perfect bead.
