These connections provide all of the valves, gauges, and couplings needed for charging Parr oxygen bombs from a commercial oxygen tank under manual control. They are made in three styles which are identical except for the coupling on the bomb filling hose. All units fit a standard 1A oxygen tank having a CGA 540 outlet with a right-handed thread. Two pressure gauges are provided. The larger gauge graduated from 0 to 55 atmospheres shows the pressure to which the bomb has been charged, while the smaller gauge shows the available pressure in the supply tank. Gas flow to the bomb is controlled by a needle valve in the gauge block. There is an automatic relief valve to prevent over-charging during the filling operation.
Oxygen Filling Connection with snap coupling for use with 1105, 1106, 1107 and 1109 bombs
