The MPS Pressure Regulator (P/N 1-0352) has 4 ports. A 1/4” NPT inlet (High Pressure) port, a 1/4” NPT outlet (Regulated Pressure 0-600psi), a 1/8” NPT gauge (Regulated Pressure 0-600psi) port, and a 1/8” NPT gauge (High Pressure) port. The ports are all labeled, HP for high pressure and LP for low or regulated pressure. The inlet port is supplied with a 1/4 NPT hex nipple installed that reduces it to 1/8 NPT male that can be installed into the bottle valve actuator of your CO2 bottle or gauge adapter of your nitrous bottle. This can be replaced with a -4 x 1/4 NPT AN fitting and use a -4 line to connect to your high pressure source. The outlet has a 1/4 NPT x ¼ poly fitting. This will go out to your low pressure device. We recommend using a small tank in conjunction with this regulator to insure an adequate volume of gas for your device.
