Perfect OEM replacement. Better be safe. Replace with electrical box (limit switch)
George•January 15, 2018
I used this on my old Campbell H 60 gal one stage compressor. It has a 150 psi release set spring and comes with pipe thread seal. For safety's sake I added some pipe thread compound. I was also replacing the electric limit switch so getting this was a compliment for safety in my 20 year old compressor
Works exactly as OEM. I tried it in my other 2 stage compressor (175 psi) and it opened at 148psi (nearly perfect setting)

heavy valve !

Very nice heavy duty valve ! In fact when I saw it I thought they had sent me the wrong valve. But it fits and is twice the size of the cheap valve that came with the compressor !! I like it !!
Good value but poor quality control

I have purchased more than a half a dozen of these devices for my compressed air lines. Even though my pressure is set at 110 PSI, I have had two of these that fail. I have had to remove them and return. Good value but poor quality control. I now buy from a different manufacturer.
Great relief valve, better than the one that came with the compressor

Very high quality relief valve. Set very accurately to the 150 psi stated. When it blows off it releases a lot of pressure in a hurry.
Tank hasn't blown up yet so...it works?

Exactly what I needed on my air compressor, the one that came on it would pop just as the pump stopped and not reset unless I pressed it in, so I got the specs off it and got this one. This one does not open (unless it needs to I would imagine) and was a perfect fit.
