About Barrel Cap
Turn a standard barrel into a pressured barrel with a barrel cap with an injector system. This type of cap enables addition of gas from a bulb to a beer barrel and usually comes in 2-inch or 4-inch sizes. It is very important to check the size, as a cap or a lever barrel tap needs to fit perfectly.
