One thing I'd like to note...
as with any slip couplings, you are not limited to the inlet, outlet, and CO2 being in line. You can rotate the T's any direction you want to get the combination that best fits your setup.
An example for my tank would be to have this mounted on the edge of the opening of my stand (Standard corner tank stand with the backs fairly open). The CO2 and inlet would be facing into the stand and the outlet would be on the outside edge pointing directly up the back side of the tank.
Also, Rex, is the outlet end a T to create turbulence? Otherwise, wouldn't a regular elbow work just as well?
