Red Ball Lock Plastic Carbonation Cap.
Are you sick of mixing up your FermZilla ports, wish there was a different colour for your liquid line? KegLand now offers the carb cap in Red!
Note: It is a multi post, so it will take both gas or liquid if you want to change it up.
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.
Yellow caps are available here
