TIG 焊槍水冷卻器轉接頭 - 美國焊槍至中式或歐式水冷卻器

The water-in and water-out threads match up perfectly with my American torch, so no wobble or leaks when I hooked it up to my Euro cooler. Took maybe five minutes to swap everything over, and the fit is snug enough that I don't worry about it backing out mid-weld.

The machined threads on this adapter are precise enough that the O-ring sealed perfectly on the first try with my 5/8"-18 LH fittings. I've been using it for weeks on a European cooler without a single drip.

I was tired of swapping out fittings every time I switched coolers, and this adapter solved that—the LH threads matched perfectly with my American torch's water-in line. Used it yesterday on a Euro cooler with 9mm connections, and it sealed tight without any leaks.
