These growler fillers are a little smaller and work well with the
Intertap faucets.
The growler filler fits inside the spout of the faucet and fills the growler from the bottom up with the length of 3/8" tubing you need to purchase separately. Always best to fill the growler from the bottom up and to have the beer and growler cold
Faucet insert is 1/2" OD
