Praxair PRS301223 Dual Gauge Regulator 3000 PSI In 50 PSI Out Gas Regulator

The Praxair ProStar PRS301223 Dual Gauge Regulator accepts up to 3000 psi from a gas cylinder and delivers a regulated 50 psi output. Its dual-gauge design provides simultaneous visibility of inlet and downstream pressures, enabling quick verification of cylinder supply and regulated pressure without disconnecting or swapping components. Identified by the PRS301223 part number, this regulator is intended for setups requiring a fixed, lower outlet pressure from high‑pressure gas cylinders. The ProStar line from Praxair, combined with the two‑gauge configuration, supports accurate monitoring during installation and operation. It is designed to be used with high‑pressure cylinder gas systems where a stable 50 psi delivery is required.
