222809 - Miller 222809 Water Hose 18LH - 10 Inch Red Coolant Return

Keep Your Torch Cool and Ready to Weld

When you are pushing high amps on a water-cooled TIG or MIG torch, the last thing you need is a leaky or burst coolant line shutting you down. The Miller 222809 Coolant Return Hose is the factory-original replacement you need to get your cooling system back to 100%. Designed specifically for Miller equipment, this hose takes the guesswork out of repairs, giving you the confidence that your rig will hold up under pressure.

Built for the Shop Environment

This 10-inch red hose handles the hot coolant returning from your torch. The red color isn't just for looks—it tells you instantly that this is your return line, making hookup quick and error-free. It comes with 18LH (Left Hand) fittings pre-installed, which is the standard connection for water outlets on most professional welding gear. Because it's a genuine Miller part, the threads are cut precisely, ensuring a tight seal without stripping or cross-threading, so you don't have to worry about coolant puddles on the shop floor.

Quick and Easy Replacement

Swapping out old, cracked, or stiff hoses is a key part of preventative maintenance. A compromised return line can restrict flow or leak, leading to an overheated power cable or torch head. With the Miller 222809, you get a direct fit replacement that routes perfectly without kinking or straining the connections. Whether you are fixing up an older cooler or replacing a damaged line on a newer machine, this hose gets you back under the hood and welding faster.
