1/4"NPT 150psi pre-set, inline regulator?

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… :slight_smile:

Doing a quick search I found the same. You might want to settle for less PSI since most horns recommend less and you’d get a few nore seconds too.

I believe Shockers are best (sound-wise) at 150? I recall reading that, somewhere…

Let me look around the shop. I think I have something for you. It will be adjustable and very high quality

That’d be much appreciated. Let me know what, if anything, you find or have in mind … and what it’ll run me.
