Product Details

One stroke of the racking cane/piston assembly will start a siphon when immersed in as little as six inches of beer or wine; less than six inches may require a second stroke. Includes a removable diverter tip to minimize sediment pickup. Plastic construction; can be disassembled for cleaning.

This high-capacity auto-siphon requires 1/2" ID siphon hose (#7106).

NOTE: It is highly recommended that you use 7/16" ID tubing with the 1/2" Auto-Siphon. Simply dip the tubing in warm water to soften it enough to slip over the end.

How easy is this???
I absolutely love this siphon. So easy to use and with the larger tubing it siphons faster. A must have for the home brewer.

Worst Auto Siphon I've Ever Seen
I had a great auto siphon for years, so sadly I assumed their design was too simple to get wrong. That was a hard lesson learned. The rubber on the bottom of the inner pump is cheap and never sits properly after you've removed it once to clean it. The rubber at the *top* of the outer pump had fell off within the first hour. It stalls, loses suction, your brew easily splatters out the top while pumping, and then it grows impossible to pump. I had to constantly stop in the middle to troubleshoot its issues, re-clean and re-sanitize it, so I've yet to see if it's cost me my two batches of beer. It was so awful that by the end I gave up and free-poured the last of my wort into my carboys, including a lot of the sediment. This isn't a siphon. It's a life model decoy, apparently designed by someone who understood the basic mechanics but has never siphoned a brew in their life. Worst product I've bought from NB in nearly 10 years. No point in a replacement - there's no fixing what's wrong with this thing.

1/2” Racking siphon review.
I have had nothing but problems with it, even with the replacement that was sent.
My old one worked really well until it broke.
My comment, leave the design alone if it works well.

Great Auto Siphon
Quickly racks from one vessel to another. Simple design with fewer pieces to have to clean. Only negative is there's no clamp that comes with it to stop the flow.

Works great and looks exactly as shown in products list.
Easy to use and makes all siphoning an easy quick process

Works Great!
I ordered this cane to speed up transfers and I’m really glad I did. The larger size really makes a difference. It’s much faster than the smaller one that came in the deluxe starter kit.

Didn't work
Got this siphon in my 1 Gallon starter kit. The included DVD didn't really go over how to attach the tube in detail, so I checked to other videos just to be sure. Seemed straightforward. Nonetheless, the "it's so easy to use, just do 1-3 pumps to start your siphon!" is not the case, as some other reviewers have stated. I had to literally pump the entire time to siphon my beer & was unable to get the last half inch of it or so. Additionally, the repeated siphoning motion would cause the open end of the tube to pop out of my gallon, consequently spraying beer all over the place. It was a lot of work, took almost an hour, and made a complete mess. I have no idea what I'm going to do when it comes time to bottle. -- The rest of the kit & DVD gets 5 stars, but my experience with the siphon was terrible.

Better than the alternative
such better than the new fancy one, even if this old-fashioned one costs more.

The best and only auto-siphon I need
I have been through a variety of siphons now and this one is the best quality. I much prefer this over any others, including the other one Northern Brewer sells. I also prefer this over the 'sterile' siphon where you blow into the vessel.

Will this fit thru the opening of the port hole in a glass 5 gallon big mouth bubbler?
Trent W on Sep 10, 2015
BEST ANSWER: The hole in the lid of the glass big mouth bubbler is a unique size slightly smaller than others. The auto siphon does not fit through that hole so to use an auto siphon

you have to take the lid off.
I love this auto-siphon, but when I was cleaning it, the cane came out of the plastic tube...and with it, a small plastic piece. Is there a way to put this back together correctly??
Kathy W on Jul 31, 2017
BEST ANSWER: If you mean the one-way valve, that happened to me too. I used a long dowel with a piece of masking tape on the end and shoved it down the tube and back into position then slowly rotated the dowel until the valve let go of the tape.
Will this fit in a 1 gal carboy?
A shopper on Oct 12, 2017
BEST ANSWER: I don't believe so. I have some half gallon growlers that I tried it in and it doesn't fit. I don't have any 1 gallon carboys to test it, but if it's a similar opening to a half gallon growler, then no. If it's similar to a 3 gallon, then yes.
The recommended tubing for this is 7/16ths, but a standard racking cane for the other end is smaller than this. I've noticed that there's no larger diameter cane available for sale. Are people just using the hose for the other end instead of a cane? Or are they using a hose clamp to stop the other end from leaking? Isn't having a smaller diameter cane on the end defeating the purpose?
R B on Jan 29, 2016
BEST ANSWER: Not exactly sure what you're asking ... "but a standard racking cane for the other end is smaller than this." Do you typically use two racking canes? One on the input and one on the output? The intended use is to put this 1/2" Auto Siphon in the higher carboy/bucket where the beer/wine is and then have it flow through the tubing into the lower carboy/bucket.
What is the difference between this product and the Auto Siphon - 5/16" racking cane? How do I choose between the two?
S F on Dec 4, 2015

The only difference is that the 1/2" is a little bigger, and flows a little bit faster. I've used both myself, and I actually prefer the 5/16 size. I find that the larger one can kink at the hose.

Hope that helps!


How long is this siphon?
C H on Dec 1, 2015
BEST ANSWER: It is about 23 inches tall. Cheers! James J.
Is there parts or a re-build kit available? While cleaning, the anti-siphon gasket went down the drain.
A shopper on Nov 27, 2017
BEST ANSWER: We do not sell replacement parts but if you contact customer service, we can look into a few options! Cheers!
