The Rhino™ oxygen pressure regulator features an all-brass uni-body construction designed to strengthen the regulator, prevent yoke damage and regulator leakage, and protect the flow selector knob from accidental adjustment. The Rhino regulator also has an integrated aluminum shroud and lens cover that shelters the gauge from breakage and contamination. A 20 micron sintered bronze gas inlet provides gas filtration and additional protection against contamination. Rhino regulators are available with up to two male DISS oxygen check valves and different flow ranges delivered through a hose barb. Gauge shroud available in different colors.
