Makes sense mate... the cutoff should be a min of 10% to about 20% below the blow off so anything between 120 and and 135 will suit admirably.
140 isn't leaving much room and would def not go any higher

140psi cutoff is pretty high. Most are set at 120psi.
I mentioned "ports" earlier, this means the hole that you thread the switch to into. If it was screwed into one ofnthey holes in the compressor then swap to a different port of the compressor. There are a few ports on the ARB compressors .
You could unscrew the gauge and fit the pressure switch there to test too.
The PRV you mentioned will bleed then blow as you describe, kind of a reverse of a staun deflator when they are nearly finished bleeding to the set pressure.
Try the switch in a compressor port and see if there is any difference .
I am conscious You are on the road mate so trying to problem solve while mobile with what you have access too.
The cylinder on thr side of the ARB Compressor is actually a little tank. The Alan key nuts in the side and ends are spare ports. Any one will do mate.
Hope this helps in some way.

Those 2 allen keys are ports that you will be able to screw you switch into.

My compressor is a Boss PX07, doesn't have any ports in it for a switch. Switch goes into receiver tank.
Higher pressure is good for air gun use.
140psi cut off not currently easily available at present.Will use a 110 on, 135 off.
Ok. The ports are out of the head. There will be more than 1. Where your hose is coming out is 1, look for a blanked off second one. In the pic below it has 3 I can see bit I expect there is probably 4. Others on google showed no port on 1 face but multiple options certainly.

You honestly won't tell the difference out of an air gun between 140 and 110psi mate. The only time you might feel the difference is running an air tool like a rattle gun anything else will just see the compressor start sooner but make little difference to operation.
Most workshop 240v compressors have a 80psi 120psi range. Don't loose sleep.

Thanks Darren. It does look like those are ports, but they are just part of the casting that are unused. Not drilled or threaded, only useable port is the one the hose comes out of. Unlike some compressors this one requires a one way valve in the hose between compressor & tank, so fitting a pressure switch into the cylinder head even if it were possible would probably not regulate the tank pressure very well, if at all.
I take your point about lower pressure cut off's.
Crikey, slightly worried now thanks for the thread @Cuppa mate! My utes ARB twin has been factory bought I believe set from the get go @ 150psi shutoff?

Issue resolved. Bought & fitted a pressure switch with a 135psi shut off. All good now.
