Uniweld’s RSO Oxygen Regulator is a single stage regulator that comes in a forged brass body, a machined brass bonnet, easy to read, 1.5 inch gauges, and protective rubber gauge boots. Regulator has a CGA540 inlet connection, “A” Right Hand 3/8 inch -24 Male outlet connection, with a delivery pressure of 2-60 PSI. Regulator is equipped with an externally serviceable pressure relief device (PRD) which protects the regulator. The PRD is not designed to protect the downstream equipment. Uniweld single stage regulators are used for general purpose applications where nominal delivery pressure changes, due to decreasing cylinder pressure, do not affect operations. Single stage regulators have greater flow capacity than two stage models.
