Tweco 1440-1135 Nylon Conduit Liner 15 Ft Aluminum Mig

Product Description

The TWECO 1440-1135 is a nylon conduit liner engineered specifically for aluminum MIG welding wire feed applications. At 15 feet in length and rated for wire sizes from 0.030 to 3/64 inch, this liner provides smooth, consistent wire delivery across the full length of the gun cable. The liner body is constructed of Teflon-style nylon material, which reduces friction and prevents the soft aluminum wire from binding or kinking during the feed cycle. A brass alloy machined stop is fitted to the back end for secure seating and positive registration inside the gun. The part number is rolled and stamped directly on the brass stop, making field identification straightforward.

This liner is designed for use in professional MIG welding environments where aluminum wire is the primary consumable. It is compatible with Tweco Professional Choice MIG guns in the 1 and 2 series, as well as the Spray Master MS250 series MIG guns. Welding technicians and fabricators working on aluminum structural, automotive, or light-gauge sheet applications will find this liner suited to demanding production and repair workflows.

Installation Notes

Installation should be performed by a qualified welding technician with the MIG welding machine powered down and the wire feed system disengaged before liner removal or replacement.

Do not use this liner with steel or flux-core wire, as it is rated for aluminum wire only. Follow the gun manufacturer's liner installation procedure for proper trim length and seating depth.
