Carbonation & Line Cleaning Ball Lock Cap – Yellow Plastic
Carbonation & Line Cleaning Ball Lock Cap – Color-Coded for Gas or Liquid Use
Quick PET Bottle Adapter for Pressurizing, Cleaning, or Dispensing
This yellow plastic ball lock cap threads onto standard 1- or 2-liter PET soda bottles, giving you a simple, portable tool for carbonating beverages, cleaning draft lines, or dispensing on the go. It’s compatible with both gas and liquid ball lock disconnects, making it ideal for multiple applications across your home draft system or fermentation setup.
Attach 3/16" or 1/4" ID tubing to the barb to use the bottle as a serving vessel or line cleaner. The barb is also Duotight compatible—just pair it with a Duotight adapter for use with EVABarrier 8 mm OD tubing.
To simplify your setup and avoid mistakes, use this yellow cap for gas connections and pair it with a red cap for liquid. This color-coded system helps prevent cross-connection in kegging and cleaning setups. Either color can be use for either gas or liquid.
