Just got a new one
Looking at my fresh new, made in China box - it says "nozzle" size (scary word) 1.4mm
The actual tip only says 10 psi (g, I guess).
I sure do wish their web site would bring up the numbers
of the 2.2 "nozzle" - usually when I talk to the HF people
I get that deafening silence or blank stare in person.
The regulator looks better than the $20 Devillbiss piece I have for my finish coat gun - but still has that 160 pound max range, 5 pounds per division markings when all you need is 23 in/ 10 out
