  • Regular price $7.99

This plastic ball lock cap features soda bottle threads, allowing you to convert a soda bottle into a pressurized growler. It is compatible with both gas and liquid ball lock disconnects. Also works well for cleaning draft lines. Simply add line cleaning solution to a soda bottle, attach it to the draft line, and open the faucet to push solution through.

When using two ball lock caps, it is recommend pairing this yellow plastic cap with a red plastic cap so you can easily identify which caps are being used for liquid or gas.

This cap can also be attached to the FermZilla collection container, enabling you to purge the collection container of oxygen.
