Garden Hose Thread X 3/8″ Barb

This adapter is a nifty little piece of equipment — Screw the threaded end into a garden hose, utility faucet, or kitchen faucet with adapter and then put some 3/8″ tubing on the barbed end. This allows you to run or spray water directly from your faucet into a carboy or bucket, making it very easy to fill fermenters, whether you are cleaning them or topping up an extract batch of beer.
