The auto siphon is a pump based siphon tube. We believe it to be the safest and easiest way to rack. We carry three different types of auto siphons.
Mini: meant for 1 gallon batches, attaches to a 5/16 hose
Small: Can fit into carboys, attaches to a 5/16 hose
Large: Fits into carboys, and Demijohns. Attaches to a 7/16 hose.
