What size PRV ?

(Spirit Lake)

Hello Thanks for your page. I have a model 47065 Harbor freight air compressor its a 21 gallon 125 psi unit. I needed a direct connection to the tank to run my double hammer air wrench. In installing the tee on the tank fitting somehow the PRV developed an internal leak. The number 8 is printed on it. I probably can get one local and avoid the shipping any ideas

Thanks and Happy Thanksgiving

It's less the size of the PRV (as long as the threads connect) than it is the cracking point.

If you don't know the cracking point of the old PRV, it were my compressor, I'd get one with a cracking point about 20 PSI over the normal cut out of the compressor.

And Happy Thanksgiving to you and yours.
