Customer Reviews (4.4 / 5 · 5 reviews)

Edward ★★★★★

The threads lined up perfectly with my Tweco #4 gun, so installation took less than two minutes. Shielding gas coverage around the weld puddle has been noticeably more consistent since I put it on.

Owen ★★★★★

Finally found a gas diffuser that actually fits my Tweco #4 gun without any wobble. The gas coverage is noticeably more even now, with no porosity in my welds. Well worth the upgrade from my old worn-out one.

Chloe P. ★★★★☆

I swapped out the old one on my Tweco #4 gun and noticed immediately less spatter on the bead edge. The fit was snug without any threading issues. It does the job well for the price.
