Pyrex 短配置夾頭主體

This collet body fits my 17 series torch perfectly and the threads engage smoothly without any wobble. It holds the Pyrex cup securely, and I've noticed better gas coverage on my stainless welds. Definitely a solid upgrade from the standard body.

Finally found the right collet body for my short configuration Pyrex cups, and it fits the torch head perfectly without any wobble. The brass threading is precise and holds the cup snug even after a few heat cycles. Exactly what I needed to get back to welding.

This is the right size for my 20-series torch running short Pyrex cups, and the threading is smooth enough that the cup seats flush without any wobble. It's held up through a solid week of shop use without the threads galling like my old one did.
