252689 - Miller AlumaPro 25ft Monocoil Liner Kit

Keep Your Aluminum Welds Flowing Smoothly

If you are running a 25-foot Miller AlumaPro push-pull gun, you know that feeding aluminum wire is an art form. The moment your liner starts to wear out, kink, or get clogged with aluminum shavings, your entire day can turn into a headache of birdnests, burnbacks, and sputtering arcs. The Miller 252689 Monocoil Conduit Kit is the factory-original replacement you need to restore that buttery-smooth wire feed you expect from your equipment.

Designed specifically for the 25-foot AlumaPro, this monocoil liner is built to protect soft aluminum wire as it travels the long distance from your feeder to the puddle. Aluminum is tricky; it wants to buckle and grab at every opportunity. This conduit provides a low-friction highway that supports the wire without shaving it, ensuring that the push-pull motors don't have to fight against drag. When your wire feeds consistently, your arc stays stable, your puddles wet out better, and you spend less time troubleshooting your gun and more time dropping dimes.

Installing a fresh conduit is one of the cheapest and most effective ways to tune up your rig. Over time, your old liner accumulates dirt, grease, and oxide dust that acts like sandpaper against the wire. By swapping in the Miller 252689, you eliminate that friction. This kit comes ready to install, so you can get back to fabrication quickly. Whether you are building boat hulls, aluminum trailers, or precision aerospace parts, don't let a worn-out liner compromise your weld quality. Stick with genuine Miller parts to keep your AlumaPro performing like new.
