Duotight Flow Stopper - Automatic keg filler

This really handy device is perfect for filling kegs, transferring from keg to keg or from fermenter to keg. Simply attach this device to the keg's gas outlet connection and once the keg is full it will stop any further liquid from flowing out of the gas outlet. This means you can simply set it and forget it and automatically fill your kegs without the risk of liquid escaping.
