Auto-Siphon 1/2" Racking Cane is perfect for transferring beer and wort from 5 gallon buckets and carboys, and its larger diameter allows it to work at twice the speed of the 3/8" Auto-Siphon. Its single stroke action and removable tip allow you to draw a siphon without disturbing sediment. It is precision designed for smooth, leak-free operation, and is easy to sanitize.
