Installed this on my Tweco #4 gun and the ceramic insulator keeps the nozzle perfectly aligned with the contact tip. Noticed less spatter buildup after a few hours of welding.

Fits perfectly on my Tweco #4 gun and keeps the nozzle securely spaced—no more arc issues during heavy welding sessions. The ceramic material feels durable enough for daily shop use.

Was a bit nervous about getting the spacing right on my MIG gun, but this insulator seated snugly and keeps the nozzle aligned without any wobble. The material feels durable enough to handle the heat, and installation took me under a minute. Exactly what I needed for the Tweco #4 setup.
