Faucet Plug / Brush
This faucet plug not only covers the opening on your faucet to keep bugs and fruit flies away from your system, but it also acts as a faucet brush to prevent protein and mineral deposits from building up in the faucet spout. It's easy to use and will ensure you end up with better tasting beer with no contaminants. The hole at the end of the cap allows you to string multiple caps together if you have a multi-faucet system, making it very handy and convenient. It's great for the home or commercial systems and works in domestic or European faucets.
