The threaded bore was a perfect match for my 26 series, and the brass construction feels much more durable than the plastic ones I've tried before. I was surprised by how quickly it locked into place.

Swapped out the old one on my 18 series water-cooled torch and it seats the Pyrex cup perfectly—no more wobble mid-weld. Fits exactly as it should with the standard config, so I didn't have to fiddle with anything.

Came to replace a worn one on my 26 torch and the fit is spot on with the standard Pyrex cup setup. The wedge seats firmly without any wobble, and it’s held up through several long welding sessions already. Exactly what I needed.
