PET bottles are readily available and inexpensive. The standard thread for PET bottles for carbonated beverages between 0-3L in size is the PCO 1881 thread. This thread type suits the carbonation caps designed by Kegland.
Note - This product includes the Tee piece only. To make it a keg system you may require an
additional purchase of a silicone tube, two carbonation caps and a soda bottle as seen in
the pictures.
