PSI On A Nathan P3?

What is a good psi to run a Nathan P3 horn with out messing it up?

I have one on my Polaris ranger crew UTV and I run it from 80-125

I was told no more than 135 psi, is that true?

I’m sure they can handle 150 but the diaphragms won’t last as long. When I got this one two of the bells had cracked diaphragms. So I chose to run it on lower pressure, and sounds better to me too.

Thanks

I have been running 200 psi for a year now with not a single problem ever.

That’s completely unnecessary on a P horn. It overblows the horn and will damage it, maybe not after a year but it will.

Even I wouldnt do that. 150 max.

i run my on 145 psi it sounds good
