Fit the 17 series torch perfectly and the threads are machined clean, so my tungsten seats snug without any wobble. Swapped it in for a 1/16" electrode and it's been holding up great through a full afternoon of welding.

After using this with my 17 series torch, the collet body fits the tungsten much tighter than my old one—no more slippage during welding. The machining is precise and the finish looks clean. Definitely worth the upgrade.

The threads are clean and snug against my 18-series torch head, no wobble when I lock in the tungsten. I grabbed the size for 1/16 electrodes and it seats them dead straight every time. Exactly what I needed to switch between air and water cooled setups without swapping out the whole torch.
