PCO1881 Carbonation Cap Tee Adapter - PET Bottle Mini Keg Connector
Turn an everyday PET soda bottle into a compact, fully functional mini keg with the PCO1881 Carbonation Cap Tee Adapter. This clever stainless-compatible tee allows you to connect both gas and liquid ball lock disconnects at the same time, something that wasn’t possible with standard single carbonation caps.
Designed specifically for PCO1881-threaded PET bottles (the standard used on most 0–3L carbonated beverage bottles), this adapter lets you build a portable keg system that’s perfect for parties, travel, camping, festivals, or small-batch testing.
PET bottles are cheap, lightweight, pressure-rated, and easy to replace—making this an incredibly practical way to serve draft beer without hauling a full Corny keg. This tee adapter is exclusively manufactured by KegLand and opens the door to true micro-keg setups using parts you likely already own.
Note: This listing is for the tee adapter only. Bottle, carbonation caps, dip tube, and disconnects are sold separately.
