Installed this on my Hypertherm torch and the gas flow is noticeably more consistent now. The threads engaged smoothly right out of the box.

Took a chance on this as a replacement for a worn-out part on my machine torch, and it fit like a glove. The gas flow has been steady through a few heavy cutting sessions, which tells me the inner channels are doing their job. Glad I grabbed it as a spare, too.

The gas channels on this ring are precisely cut, which made a noticeable difference in arc stability right away. Installation was straightforward, and it fits my machine torch perfectly for smooth cutting.
