Auto Siphon
Available in three sizes, Mini & Regular (3/8") and Large (1/2").
The Auto Siphon pump allows you to easily rack your liquid to another container. With a single pump you can begin the transfer, rather then sucking on the end of the hose to begin the process, which can potentially contaminate your brew.
Mini & Regular (3/8") uses 5/16" tubing
Large (1/2") uses 7/16" tubing
