Alexander ★★★★★ Oct 22, 2026

This adapter fit my 20 series torch perfectly and the large diameter hole kept the tungsten from wobbling. Even with heavy use, the threads engaged smoothly without any binding.

Alexander T. ★★★★★ Oct 21, 2026

I needed a solid adapter for my water-cooled TIG torch, and this large diameter tungsten piece fits perfectly with no wobble. The precision machining on the threads is excellent, and it locks in securely every time.

Olivia H. ★★★★★ Oct 20, 2026

The threads on this adapter are machined smoothly—it screws onto my 26 series torch without any wobble. Perfect fit for swapping between different torch heads without any gas leaks.
