Violet F. ★★★★★

Finally, a gas diffuser that actually seats flush without cross-threading on the first try. The front M11 threads are nice and consistent, so swapping nozzles is quick and hassle-free. A solid, simple upgrade for my Tweco gun.

Stella L. ★★★★★

Fits perfectly on my Tweco #1 gun, the M10 x 1.5 rear thread screwed on smooth without any cross-threading. The front M11 threads matched the nozzle just right, so no more gas leaks at the tip. Solid little part for the money.

Grace ★★★★★

M10 x 1.5 rear threading and the M11 front match exactly what my old one had, so it swapped in without any fuss. The gas flow seems steady too, no sputtering at the weld puddle.
