"This regulator is not good:

When installing, the instructions are very confusing when dealing with the red safety valve. If improperly installed it will leak after 50psi. You have to remove the red cap but not the internals and screw all the brass parts together first to your desired pressure limit OFF of the tank then put the red cap on then the regulator onto the tank.
The set screws on the side need to be all the way in or it will leak at any pressure.

When I got it installed properly I went to adjust the pressure up to 180 psi. Got to 170 and went an 1/8 of a turn further. The pressure rose so high it broke the guage on the side. This also broke the top portion of my tank because now I need a regulator on the tank or it will leak; it did not do this before and I could take my other regulator on and off with ease. When I turned the pressure off like you are supposed to before removing the regulator, I could not easily bleed the air out by adding a remote line to the port. When I went to take the unit off my tank, I still was hearing air escape. When I completely unthreaded the regulator it had a large poof of air like removing a remote line and my tank was still spewing a small amount of air from the top.

When the air started spewing out from any loose ports the gray finish turned brown probably due to machine oil from manufacturing.

This product does not hold 225psi on a topman 48ci 3000psi tank. It will hold steady around 160-170 but no more.

I do not recommend this product for not working to pressures as advertised, breaking the guage because it does not work as advertised, and breaking a part on my tank.
