Struggling with aluminum wire feeding issues? The Miller M1421 Teflon Liner is your solution for consistent, trouble-free welding. Aluminum wire is soft and difficult to push, often leading to frustration when it binds or kinks inside your MIG gun. This Teflon liner is specifically designed to solve that problem by providing a slick, low-friction surface that lets the wire glide effortlessly.
This 10-inch liner is typically used as a jump liner or neck liner, fitting into the front end of your gun to guide the wire through tight bends and angles. It is sized perfectly for .047" (3/64") and .062" (1/16") wires, making it a versatile addition to your spare parts kit. Whether you are repairing a boat, working on a trailer, or fabricating custom aluminum parts, having a fresh liner installed can make the difference between a perfect bead and a bird-nest mess.
Don't let feed problems slow down your production. Worn liners are a leading cause of erratic arcs and burn-backs. By swapping out your old liner for a new Miller M1421, you restore the performance of your welding gun. It's a small investment that pays off in smoother welds and less downtime clearing jams. Keep your aluminum operations running at peak efficiency with genuine Miller replacement parts.
