The Standard Gas Mixing Manifold comes ready to partial pressure blend Oxygen and Oxygen Compatible Air (OCA) to create Nitrox. The heart of the system is a 10 port, chrome plated brass manifold. Two metering valves are included. One on each end of the manifold. Each metering valve has a check valve to prevent back flow into the supply gases. The metering valves are fitted with a male JIC connector allowing simple connection into gas supplies. Pressure is monitored thru Global's #45305OX digital mixing gauge. Also included is a #45350OX mixed gas filling whip which consists of a 5,000 psi rated Teflon core hose five feet long, a 300 Bar DIN fill attachment with bleeder and a DIN to yoke converter. Wall mounting is easy with the included #45217 mounting bracket. The 6 extra ports are plugged if extra mixed gas filling whips are not utilized.
