This plastic carbonation cap has been designed to suit soda bottes, coke bottles, and FermZilla lids. If you have a keg system you should have at least a couple of these as they are so useful for quickly carbonating uncarbonated beer or correcting carbonation in small amounts – also useful for puching cleaning or sanitising solution through your kegging system lines.

Both Liquid and Gas ball lock compatible.

This carbonation cap is also suited to any of the FermZilla products such as the FermZilla Pressure kit.

This product is made from high quality engineering plastic and will last a very long time. It’s chemically resistant and also designed ot resist impact and physical damage.

The thread specification on this product is the PCO 1881 (AKA Coke bottle thread)
