The Oxygen Regulator is designed to reduce the pressure and control the flow of oxygen from an oxygen cylinder or tank.

An oxygen flow control regulator is a pressure-reducing device, which lowers the oxygen pressure from a cylinder to levels, which can be safely used by the patient. Oxygen Regulators are intended for the administration of oxygen to patients who need increased oxygen levels to improve their breathing conditions

This oxygen regulator uses an advanced, patented Intelliflo disc to regulate oxygen flow down to 1/32 LPM with very tight tolerances. It features a brass core, skidproof knob and body that won't peel flake or wear off. All metal anodized aluminum construction is more durable and will not rust, plus the gauge protector helps prevent damage.
