K4544-7 - Lincoln Electric 7ft Water Hose Kit with Quick Disconnects

Streamline Your Water-Cooled Setup

As a professional welder, you know that a water-cooled torch is a game-changer for high-amperage MIG and TIG applications, but dealing with the plumbing can often be a hassle. The Lincoln Electric K4544-7 Water Hose Kit is designed to take the headache out of connecting your cooler to your torch. No more fiddling with hose barbs, worm gear clamps, or leaky connections that leave puddles on your shop floor. This kit is all about plug-and-play efficiency, letting you focus on laying down perfect beads rather than troubleshooting your equipment.

The standout feature of this kit is the pre-installed Quick Disconnect system. You get two 7-foot hoses: one for the supply and one for the return. The end that connects to your water cooler features a male quick disconnect, while the end connecting to your torch or wire feeder utilizes a female quick disconnect. This snap-on, snap-off functionality means you can set up your rig in seconds. When the shift is over or you need to switch to a different torch, disconnection is just as fast and completely tool-free. The fittings are precision-machined to seal tight, ensuring that your coolant stays in the line where it belongs.

At 7 feet long, these hoses give you the freedom to position your equipment exactly where you need it. Whether your cooler is integrated into the power source cart or sitting on a bench, you'll have enough length to route the hoses cleanly without tension. The hoses themselves are built tough to survive the welding environment—resistant to abrasion, cuts, and the occasional hot spark. They are flexible enough to route easily but sturdy enough to resist kinking, ensuring uninterrupted coolant flow.

Designed specifically for the Flextec 500 but compatible with many standard water-cooled setups, this kit is a must-have for any welder running high heat. Don't let an overheating torch slow you down or burn your hand. Upgrade your cooling loop with the Lincoln K4544-7 and experience the convenience of a professional-grade connection system.
