Finally found the part

[Dauntless152]

Been looking for a long time to find the right part to just seamlessly run constant air to my P 68.
here it is. 10/32 to 1/4 . No leaks , works perfectly.

What's the whole set like, on/off bottom of grip, small tank Hawaiian style?

Bottom line to an on off , waiting on a longer macro line , then a 48 3000 .

Back in the day, we would drill out that 10/32 to 1/8npt...... which was totally unsafe. Not nearly enough metal, but we did it anyway. Good times.
