The patented design of the ST Series Regulators allows for the use of conventional regulators with a high pressure cylinder. These regulators deliver high flow rates while reducing high cylinder pressures to lower pressures that conventional regulators are designed to handle. This eliminates the need for a second set of equipment when working with high pressure cylinders. To install, remove the CGA inlet connection from the regulator and replace it with the ST regulator.

The RHP Series High Inlet/High Delivery Regulators are designed for use with high pressure cylinders (up to 6000 PSIG) and are capable of delivering up to 4500 PSIG. Select models include a delivery flow gauge or flowmeter for MIG and TIG applications. Certain models feature Western's "Pressure Compensated" design for applications that require high flow rates, this design provides more consistent delivery pressure by minimizing fluctuation over a wide range of inlet pressures.
