The Fermtech Auto Siphon is a handy tool used in transferring and racking. Instead of manually starting a siphon as you would with a racking cane, all the auto siphon requires is a few quick pumps! Much easier and more convenient than a racking cane, this auto siphon works with 1/2" ID siphon tubing for quicker transfers. Use one of these today and you'll never go back to a racking cane!
