Customer Reviews (4.6 / 5 · 5 reviews)

Ellie ★★★★★

Argon coverage is noticeably smoother on my 9 series torch with these diffusers, and the threads seated cleanly without any wobble. Having the 2-pack means I always have a spare ready when the shop gets busy.

Nicholas ★★★★★

The 1/8" size fits my 9 series torch perfectly, and the gas lens diffuser gives a much smoother argon flow on aluminum welds. Having two in the pack is a solid backup for when one gets clogged mid-job.

Steven ★★★★★

Two of these in the pack means I’ve got a spare ready when the threads finally wear out on my current one. They seat into the torch body with zero wobble and the 1/8” size matches my setup perfectly. Solid value for the price.
