Calgaz offers a choice of standard high pressure regulators for use with our High Pressure Cylinders (HPC’s).  The R31 is a dual-stage, high purity style regulator, designed for applications where a consistent outlet pressure and flow is desired. It is also supplied with 1/4” NPT Female inlet and outlet fittings. R31 is also available in nickel-plated brass and stainless steel.  Calgaz regulators are designed, meticulously hand-assembled, then rigorously inspected by highly experienced professionals in our Cambridge, Maryland facility. Every single regulator is function tested and leak checked, with rigid quality controls in place. ​​​​​​​All stocked R21 and R31 regulators are supplied with 1/4” NPT Female inlet and outlet fittings. Calgaz can supply connectors to fit British Standard (BS), DIN and CGA cylinders. For more information or requests regarding other regulators for HPC applications please contact us.
