I bought the Milton regulator because it was supposed to be a quality American product. I filled it with copper (photo). When I first pressurized the system to 90psi from the remote compressor, everything worked fine. When I finally ran the factory compressor and got to 140psi, it started leaking until the pressure dropped below 100psi. This regulator is designed for an operating pressure of 250 psi. So there is no excuse. I don't know what kind of guarantee, but I'd like a free kit. I think I'll call Milton in the morning. If they are decent and if it fixes the problem I will up the ante to two stars!
