Keep your welding operations running smoothly with the Tweco 42-40-15 Conduit Liner (Stock Code: 1400-1123). Designed as a direct replacement for 15-foot Tweco MIG guns, this liner is an essential consumable for welders running standard mild steel or flux-cored wires. It is sized perfectly for wire diameters ranging from 0.035 inches to 0.045 inches, covering the most common applications in general fabrication and manufacturing.
The liner is manufactured from spirally wound, zinc-plated music wire. This construction provides the necessary rigidity to prevent the liner from collapsing while maintaining enough flexibility to navigate the cable assembly. The zinc plating acts as a lubricant and a rust inhibitor, ensuring that the wire slides effortlessly through the gun cable. This reduces the load on your wire feeder motor and helps prevent the dreaded "burn-back" caused by feed interruptions.
This 42 Series liner is the standard fit for many legendary Tweco models. If you are using a Tweco Spray Master 250, 350, or 450, or a Classic Number 2, 3, or 4 gun with a 15-foot cable, this is the correct replacement part. It can also be trimmed to fit shorter cables if necessary, following standard maintenance procedures.
Specifications:
Don't let a clogged or damaged liner compromise your weld quality. Replace it with genuine Tweco parts for guaranteed fit and performance.
