Calgaz offers a choice of standard high-pressure regulators for use with our High-Pressure Cylinders (HPCs).
The R21 is a single-stage, high-purity regulator designed for low-pressure applications. The R31 is a dual-stage, high-purity style regulator designed for applications where consistent outlet pressure and flow are desired. Both R21 and R31 are available in nickel-plated brass and stainless steel.
All stocked R21 and R31 regulators are supplied with 1/4” NPT Female inlet and outlet fittings. Calgaz can supply British Standard (BS), DIN and CGA cylinder connectors. We can also adapt R21 and R31 to fit non-refillable cylinders.
All regulators carry a 24-month warranty.
