Miller 36-Inch Coolant Hose LH Thread to Quick Connect

Keep Your Cool with the Miller 201430 Replacement Hose

When you are in the middle of a heavy welding project, the last thing you need is a leaky coolant hose shutting down your operation. The Miller 201430 Hose Assembly is the direct replacement you need to get your water-cooled system back in top shape. Designed specifically for Miller welders and coolers, this 36-inch hose bridges the gap between your coolant supply and your equipment with the reliability you expect from the brand. Whether you are replacing a worn-out line on a TIG Runner or setting up a new Coolmate unit, this hose is ready to go right out of the package.

One of the standout features of this hose is its connector configuration. On one end, you have a standard Left-Hand (LH) thread. If you've ever fumbled around trying to figure out which hose goes where, you'll appreciate this design—the reverse thread ensures you never accidentally plug your water line into your shielding gas outlet. On the other end, a Quick Connect fitting makes snapping the hose into place incredibly easy. No more wrestling with wrenches in tight spaces; just click it in, and you have a secure, leak-free seal that stands up to the pressure of your cooling pump.

Water-cooled torches are essential for high-amperage welding, allowing you to weld longer and cleaner without the torch getting too hot to handle. However, the system is only as good as its weakest link. Old, cracked, or stiff hoses can restrict flow or burst at the worst possible moment. By swapping in a fresh Miller 201430 hose, you ensure consistent coolant delivery, protecting your expensive torch head and power cable from heat damage. At 3 feet long, it's the perfect length for most cart-mounted or benchtop setups, keeping your workspace tidy and efficient.
