16401340 - Tweco 64-60 Conductor Tube for Spray Master 450, 60 Degree Bend

Get Your Spray Master Back in Action

If you are running a Tweco Spray Master 450 and your neck is beat up, bent, or just clogged beyond repair, the Tweco 1640-1340 (64-60) Conductor Tube is the exact replacement you need. This isn't just a piece of pipe; it's the backbone of your MIG gun's front end. This specific model features a 60-degree bend, which many welders prefer for bench work or when welding in positions where a steeper angle helps keep your wrist straight and comfortable. It gives you that extra bit of reach and visibility into corners that a standard 45-degree neck might miss.

Tweco's Spray Master series is legendary for being tough, and this conductor tube lives up to that reputation. It is built to handle the heat of 450 amps, making it perfect for heavy fabrication, structural steel, and spray transfer modes where things get hot fast. The heavy-duty insulation on the outside protects the neck from shorting out if you accidentally bump the workpiece, and it stands up well to the inevitable spatter and abuse of a shop environment. Inside, the smooth path ensures your wire feeds consistently, reducing those frustrating burn-backs and stuttering feeds.

Swapping out a conductor tube is one of the easiest ways to refresh a tired MIG gun. Over time, the threads for the diffuser can get stripped, or the internal liner path can get grooved. Installing a fresh 64-60 tube restores the electrical connection and gas flow to factory specs. Whether you are repairing a gun that took a dive off the bench or just configuring your setup for a specific job that requires a 60-degree angle, this genuine Tweco part ensures everything fits tight and welds right.
