The ceramic body is noticeably more durable than the old one I had, and it mates perfectly with the gas diffuser and nozzle combo I use. After a few heavy welding sessions, it still hasn't cracked or loosened up.

Fit perfectly on my Tweco #2 gun without any filing or forcing. The ceramic body feels sturdy, and it's holding up well after several heavy welding sessions.

I was expecting the usual struggle to seat the insulator, but this one fit the gas diffuser and contact tip groove perfectly on my first try. Nozzle holds steady now during heavy welding, which is all I really needed.
