Emma A. ★★★★★ Oct 22, 2026

The 2-pack is a solid deal for the price, and the #12 size fits both my 9 and 20 torches without any adapter hassle. Gas coverage on stainless has been noticeably cleaner since I switched, less weld contamination.

Jacob ★★★★★ Oct 21, 2026

Swapped out my old setup for these #12 gas lenses on the 20 series torch and noticed a smoother arc immediately. The 2-pack is great for keeping a spare ready to go.

Thomas S. ★★★★★ Oct 20, 2026

The fit on my 9-series torch was perfect, and the two-pack means I always have a spare on hand for quick swaps. Argon coverage felt noticeably smoother on stainless, so my welds came out cleaner with less cleanup.
