ABSTRACT:
Several high pressure gas cylinders are attached together in a pack, each container having a valve at one end that controls flow of gas from the cylinder and each valve having a removable valve control handle, the cylinders being arranged coextensive and contiguous in the pack with all cylinder valves at the same end of the pack, a gas manifold at that end of the pack having a gas input for each cylinder and a gas output for feeding gas to a utilization device, a gas line from each cylinder valve to one of the manifold inputs and a manifold valve at the manifold output, so arranged that the manifold valve controls gas flow from the pack of cylinders to the utilization device and the cylinder valves control gas flow from each cylinders to the utilization device. In a preferred embodiment, a protective valve cap is provided for each cylinder valve secured to the cylinder and the valve control handle therefor is removable from and attachable to the valve without removing the cap, whereby all cylinder valve control handles in the pack can be removed and the valves are at all times protected by the caps, even while the pack provides gas to the utilization device, and so damage to the valves and/or tampering with the valves is prevented.
