Scarlett ★★★★★

The gas flow on my RSG500 is much more consistent now, and I noticed less spatter on my last job. It threaded on perfectly without any hassle—definitely solved the coverage issue I was having.

Emily X. ★★★★★

Swapped my old one for this because the RSG500 needed a new diffuser anyway, and the gas coverage is noticeably smoother around the weld bead now. The threads lined up without any fuss.

Lily F. ★★★★★

The fit on my RSG250 was perfect right out of the box, no fiddling needed. Gas coverage is noticeably more consistent than with my old setup, and the threads feel machined well.
