The type of take-off (branch fitting) used on a piping system is specific to the flow medium.

If the medium is water, branch tees are OK.

If the medium is gas pressurized to liquid (CO2, refrigerant, etc.), take off from top of pipe to get gas, bottom to get liquid.

Size take-offs using formulas relevant to medium (water = Hazens and Williams)
