42V73 - ESAB 42V73 Nylon Conduit Liner for 3/32 Aluminum Wire (11ft)

Smooth Aluminum Feeding with the ESAB 42V73

If you are welding aluminum, you know that wire feeding is half the battle. The ESAB 42V73 Nylon Liner is your best defense against the dreaded "birdnesting" and erratic feeding that plagues aluminum MIG projects. Designed specifically for 3/32-inch wire, this liner replaces standard steel conduits that are too abrasive for soft aluminum alloys.

The 11-foot nylon construction provides a slick, low-friction path for your wire. This is crucial because aluminum wire is soft; if it encounters resistance, it tends to buckle at the drive rolls or shave off inside the liner, clogging the gun and ruining your contact tips. By switching to this dedicated nylon liner for your ST-21M gun, you ensure that the wire glides smoothly right to the puddle, giving you better arc control and cleaner welds.

Installation is straightforward and matches the fit of your original equipment. Whether you are fabricating heavy aluminum structures or performing specialized repairs, trusting the right liner for the material makes all the difference. Don't let feed issues slow you down—equip your torch with the 42V73 and experience the difference a proper conduit makes in your aluminum welding performance.
