14411135 - Tweco 44N-116-15 Nylon MIG Gun Liner for 1/16" Aluminum Wire

Stop Bird-Nesting with the Right Liner

If you are welding aluminum, you know the headache of a bird-nest at the drive rolls. It usually happens because the wire is dragging somewhere in the gun cable. The solution is simple: get that steel liner out of there and install the Tweco 1441-1135 Nylon Conduit. This liner is specifically built for 1/16" aluminum wire. The nylon material is slick, allowing the soft wire to slide through the 15-foot cable without the friction that causes it to bunch up and tangle back at the feeder.

This is the genuine Tweco 44N-116-15 liner, designed to fit your trusty Tweco No. 4 or No. 5 MIG gun. It’s 15 feet long, so it covers the standard cable length perfectly. When you switch from steel to aluminum, swapping your liner is the most important step. A steel liner acts like a file against soft aluminum, shaving off tiny flakes that eventually clog the liner and ruin your contact tip. This nylon liner prevents that shaving, keeping your wire clean and your feed smooth.

Installation is easy. Just pull your old liner, slide this one in, and trim it to the correct stick-out length for your diffuser and tip setup. It’s a small investment that saves you hours of frustration and wasted wire. Whether you are fabricating aluminum trailers, repairing boat hulls, or doing custom automotive work, this liner ensures your machine runs as smoothly as your hand moves.

Why Welders Choose This Liner:

• Smooth Feeding: Slick nylon surface eliminates drag on soft aluminum wire.
• Perfect Fit: Designed for standard 15ft Tweco guns running 1/16" wire.
• Cleaner Welds: No steel shavings contaminating your weld pool.
• Less Downtime: Drastically reduces the chance of bird-nesting at the feeder.
