Where to buy that adapter female 16x1.5mm / male 1/2 NPT

[Boyan Silyavski]

Hi guys,

i believe i mislead you, also due to a lack of sleep

The connector is smaller than the m16x1.5 chinese connector.

I was browsing some forums for an answer and somewhere i read that 1/2 NPT is the standard for the american made plasma machines so i assumed without thinking it further that this is the case here. Cause the Thermal Dynamics universal torch sells or in ATC Connection or in something called O2B Connection . I bought mine with the ATC connector which is proprietary, looking something like a Mig Euro-plug and additionally bought the short adapter which adapts it to something which i assumed was the 1/2 NPT

Now here are some photos, the thread seems similar like the 1.5mm thread but this i can not confirm as i dont have all thread gauges and the ones i have dont enter properly so its difficult for me to judge.

Maybe hopefully its some popular thread. Now my bad was that i went to industrial shop and there was a fitting that almost fit at the side of the hose, but i did not ask him which size was, as i was still under the 1/2 NPT impression.


Right photo is the new one, left is the bigger Chinese 16x1.5mm


PS.Just checked again with the thread gauges i have, the thread seems more near 1.25mm size or 20G 1/4 BSW
