Siphon tubes are needed for draining carboys, kegs, and other vessels that lack a valve. All our siphon tubes feature a curved top, and a sediment avoidance fitting at the bottom so they can rest on the bottom of the carboy. Plastic siphon tubes are economical, and made of clear plastic for a good view of the beer. Get this 24” siphon tube for draining 5 and 61/2 gallon carboys, while a 30” siphon tube is handy for draining 5 gallon Cornelius-type and 15 gallon (cut off) kegs. Order needed 3/8" siphon tubing (not included) below.
