I’m looking for a 1/4"NPT 150psi pre-set, inline regulator. I’ve seen 100psi, but not 150; I’m only finding variables that max at 150.
I’ll take 1/2"NPT if I can get it, as well. What I’m trying to avoid is a gauge, set screw, or bleeder hole, as this application is in the engine compartment where space is tight and vibration is expected.
Anyone seen anything like this … or something else that might be usable for the application? I’d like to conserve air to get a few more seconds out of the horns, if possible…
