This Tee Piece helps make a really small and useful keg system out of PET plastic bottles. Great for taking beer to a party or making your own micro/portable/mini keg system.

PET plastic bottles are readily available and inexpensive. The standard thread for PET bottles for carbonated beverates between 0-3L in size is the PCO 1881 thread. 

Historically you would only be able to place a black or grey ball lock disconnect onto these fittings one at a time. This tee piece now enables you to attach both a liquid and gas disconnect to the bottle at the same time so you can essentially use a common PET bottle as a keg.

Note: The PET soft drink bottle, carbonation caps and dip tube shown in pictures are sold separately.
