14401012 - Tweco 44N-116-15 Nylon MIG Liner for 1/16 Aluminum Wire - 15ft

Smooth Aluminum Feeding

Anyone who has welded aluminum knows the frustration of "bird-nesting" at the drive rolls or an unstable arc caused by poor wire feeding. The Tweco 44N-116-15 Nylon Conduit Liner is your first line of defense against these common headaches. Designed specifically for 1/16-inch aluminum wire, this 15-foot liner replaces your standard steel liner to provide a slick, low-friction path for the soft wire to travel through your MIG gun.

Why Nylon Matters

Steel liners are great for steel wire, but they act like sandpaper on soft aluminum. They can shave off tiny particles of aluminum that clog the liner and the contact tip, leading to burn-backs and downtime. This Tweco nylon liner eliminates that metal-on-metal abrasion. The result is a wire that slides easily, requiring less drive roll pressure and delivering a consistent speed to the weld puddle. This consistency is key to achieving the high-quality, aesthetic welds that aluminum projects demand.

Genuine Tweco Quality

Don't compromise your equipment with generic fits. This is a genuine Tweco part (Stock No. 1440-1012), ensuring perfect compatibility with your Tweco MIG gun. Whether you are fabricating boat hulls, repairing trailers, or working on custom automotive parts, swapping to a fresh nylon liner is one of the cheapest and most effective maintenance tasks you can perform to improve your aluminum welding performance immediately. Keep your arc smooth and your frustration low with the right conduit for the job.
