Uniweld RHP400 Nitrogen Regulator for 0-400 PSI Delivery Pressure

The Uniweld RHP400 is a durable nitrogen regulator designed with a brass piston and diaphragm, featuring a delivery pressure range of 0-400 PSI for purging and pressure testing air conditioning and refrigeration systems. The regulator boasts a CGA580 inlet connection and a 1/4 inch male flare outlet connection, along with a self re-seating relief valve, though it is not designed to protect the downstream system.

For easy readability, the regulator is equipped with a 2-inch contents gauge (0-4000 PSI, part no. G7SD) and a delivery gauge (0-600 PSI, part no. G8SD), both with protective rubber gauge boots (part no. GB20S). The smooth and accurate delivery pressure adjustment is facilitated by a large brass tee handle with a stainless steel pressure adjusting screw and a regulator bushing that prevents galling.

The Uniweld RHP400 regulator can also be used with CO2 by employing the Uniweld part no. F36 adaptor, which allows the connection of a CO2 cylinder (CGA320) to the nitrogen regulator (CGA580). This accessory, however, must be purchased separately.

In summary, the Uniweld RHP400 is a durable and versatile nitrogen regulator, designed with a brass piston and diaphragm, and offering a delivery pressure range of 0-400 PSI. It features a CGA580 inlet connection, a 1/4 inch male flare outlet connection, and easy-to-read 2-inch gauges with protective rubber boots. The regulator also includes a self re-seating relief valve and a smooth, accurate delivery pressure adjustment mechanism, making it a suitable choice for a variety of air conditioning and refrigeration system applications. Additionally, the regulator can be adapted for use with CO2 by utilizing a separate Uniweld adaptor.
