16501101 - Tweco 65-45 Replacement Gooseneck 45 Degree

Restore Your Tweco Gun's Performance

If you are running a Tweco No. 5 or No. 6 MIG gun, you know these tools are built like tanks. However, even the toughest gear takes a beating. The conductor tube (or gooseneck) is often the first part to suffer from drops, hammer usage, or just thousands of heat cycles. The Tweco 1650-1101, also known as the Model 65-45, is the direct replacement 45-degree neck for your heavy-duty setup. When your old neck gets bent out of shape or the threads for the diffuser get stripped, it ruins your wire feed and makes changing tips a nightmare. Swapping in a fresh 65-45 tube brings your gun back to factory specs instantly.

This tube features a standard 45-degree bend, which is the go-to angle for most welding positions. It gives you the right amount of curve to see the puddle clearly without forcing your hand into awkward positions. Because it is designed for the high-amperage No. 5 and No. 6 guns, it has a thick-walled copper construction that handles the heat without melting down or getting soft. It acts as the highway for your welding wire; a straight, undamaged tube means less friction on the liner and smoother wire feeding, which translates to a stable arc and less frustration at the trigger.

Don't struggle with a beat-up torch that feeds wire poorly or gets too hot. This genuine Tweco part ensures your gas diffuser screws on tight and your gas flow remains laminar. Whether you are welding thick structural beams or heavy plate, having a reliable conductor tube is key to keeping your arc smooth. Keep a spare 1650-1101 in your tool crib so you aren't caught off guard when a forklift runs over your torch or a thread finally gives out. It’s a quick fix that makes a massive difference in how your gun feels and performs.
