Yes, the first one I bought broke before I could use it when I dropped it while it was slick with sanitizer; but as far as I can see, these type siphons are the only game in town; so I bought another and now I have a working one and some spare parts; found that it worked better by starting flow with 3 or 4 short pumps, not one or two l-o-n-g ones; I clean it before and after use, disassembling every time; i keep the end out of the schmutz at the bottom of the fermenter to prevent slow flow or clogging; the more I use it, the better we get along.

Works but falls apart in short order
It's a fine siphon while it lasts, but the seal on the piston part breaks down very easily. I've had two. NB replaced the first one (on the left in the photo) when I complained but did not replace the second (on the right in the photo). I will not buy this product again.
It falls apart.

When I got this siphon I was super stoked. It is definitely more sturdy than other siphons out there but going off of the other reviews mine was not as airtight. Not a huge issue but when I was going to clean mine out, trying to get the inside part out and back in is so incredibly hard that my seal broke. See picture. I read the directions to a T. I’m so disappointed. Now I’m out 12$ and I have to push back on my timeline to rack the secondary. Quite an inconvenience.
Rubber seal broken when trying to put inner tube back in.

Not good
Difficult to use. I'm going back to the cheapie one I'm replacing it with. Does not need to be this complicated an item, makes it much more difficult to use, and the plunger you have to force down the tube. Also, not the threaded plastic could harbor nasties if not cleaned properly. Who designed this?

Excellent siphon
Product works as described and is high quality. I like how you can take all the pieces apart for easy cleaning

Stronger, yes. More robust, but clunky and not as air tight as the cheaper ones.

not great
i bought this to replace a slightly more expensive auto-siphon and that was a mistake. first batch, siphoned fine. took apart, cleaned all pieces and sanitized. Second use, took apart, sanitized, put back together and went to use and the siphon wouldn't pump any liquid what so ever... took apart, made sure all was installed correct and all parts were, re-sanitized and tried to siphon again, same crap, not a good enough seal to actually pull the beer up and out. the gasket at the bottom of the inner-tube is flimsy and i found it was very difficult to get it back inside the outer tube, even with sanitizer for lubricant. i will go back to the more expensive siphon, that always worked and although it cracked, at least it worked.

Received product with our starter kit. Worked poorly the first time and even worse the second go around. So much air (and tried tightening and loosening the end as an experiment after we realized our batch was ruined anyways with no improvement).

Sounds like you may have a bad seal and need a replacement. If you contact customer service we can get you a replacement.

Air bubbles
Used it for 8 months. All of a sudden is starts sucking air bubbles when transferring to secondary. I disassembled it and checked the cap adjustments and seals. Still could not get it to not suck air. Seams like the seal in the tube was letting air through and beer up the tube. Disappointed this product did not last. It oxygenated my whole batch of white house honey porter. Going to upgrade to the better one.

Response from Northern Brewer
Air bubbles during racking are most commonly co2 coming out of solution, not actually oxygen. This is will not harm the beer at all.

Would give a zero rating if i could. Received my starter kit and was very excited to start brewing. I brewed the block party amber ale that came with the kit and it was time for bottling. Went to use the autosyphon after cleaning and sterilizing it and it wouldn't work..... I tried adjusting the end cap and whatever else I could do in order to get it to work. After almost an hour i finally got a good enough flow to transfer the beer. Hopefully the beer still turns out after everything I had to do. This would not create any suction and i had to get it as far as I could into the bucket which stirred up the yeast cake. Pretty sure this thing ruined my first batch of beer.

I am curious if there is a trick to using this so it doesn't introduce massive amounts of air bubbles while siphoning? I had to stop/start the siphon about a dozen times the very first time I used it due to an insane amount of air coming through the line. I still bottled the beer (my first batch - let's just say my hopes are NOT high), but I was so disappointed by how much air came through. I know the bottom is adjustable, so I'm curious if I should tighten it down more to slow the siphon down? Any help would be greatly appreciated.

BEST ANSWER: It sounds to me like yours is not working right! It should not leak air into the siphon hose as it moves liquid, that would indicate that there is an air-leak in the seal on the inner tube of the siphon, or air is leaking at the hose connection to the siphon. If 5/16" tubing is used, it should not leak at the hose connection, as it is very tight, so it may be that it's leaking at the flexible seal on the internal tube. If that's the case, we can replace this unit for you. Take a look at yours and let us know if that seems to be the case, we would gladly send you a new one! -Mike W, Northern Brewer
What is the temperature limit on this siphon? Can it be used to transfer liquids that are heated to 180 F degrees?
C A on Jun 7, 2016
BEST ANSWER: I wouldn't try. I had the older version of the siphon and used it for warmer wort temps. The bottom of it warped and it had to be replaced.
I have been having trouble getting my Rack Magic siphon to start after two pumps in some of my beers. What is going wrong?
C O on Apr 7, 2016
BEST ANSWER: There are a few things you can do to ensure that your siphon will start more quickly:

1. Make sure that you have wet the seal in your siphon, while you sanitize. That will make it easier to pump the siphon and go through a full sweep of the pump.
2. If you have disassembled the bottom tip of your Rack Magic for cleaning, make sure that the gap at the bottom tip is at least 1/8" after you have reassembled.
3. Do not stick the tip of the Rack Magic directly into the trub that has settled at the bottom of your beer. If there is too much trub to rest the tip on the punt at the bottom of your fermenter, hold the Rack Magic tightly against the side of your fermenter with one hand while you pump with the other. This will help prevent the trub from getting sucked into the Rack Magic and clogging the siphon. It will also keep the Rack Magic from stirring up all of the trub that you have let settle out.

That should help get the siphon flowing. If not, please contact us to help further.
Hope it helps,

The first time I used this, I had very little suction. At some point, I gave up and dumped the rest of the wort out. I may have reassembled something incorrectly after sanitizing. Do you have any ideas?
S A on Feb 27, 2016

Sorry to hear about that. Were you able to get any beer into it all? Perhaps the bottom cap was screwed to tight. I would also check the gasket on the end of the inner tube for damage. I'd also try it out with water to see if you can get it to work. If you can't, let me know and I'll have a replacement shipped out for you.


what is the outer diameter of this? will it fit in the mouth of a 1 gallon glass jug?
P L on Feb 16, 2016
BEST ANSWER: The widest part is the plastic fitting on the bottom. This is 1.017 inches in diameter (measured with my calipers). I wonder, however, why you need a siphon to empty a 1-gallion jug. Couldn't you merely decant by pouring? The housing of this device is 23.5 inches long. Seems like it would be cumbersome, using it with such a small jug.
What size clamp do I need for this? I'm guessing the 1/2 inch, but I want to be sure before I order.

L U on Feb 15, 2016
BEST ANSWER: You'll want to use the 5/16" AutoSiphon clamp, part #7151. This will fit onto the new Rack Magic Siphons. Have a good day! -Mike W, Northern Brewer
Is this the product that comes with the new small batch kits? I had issues with it and reviews seem to imply I am not the only one...
A shopper on Aug 29, 2017
BEST ANSWER: Yes I bought the same one and it has never worked yet. It never seems to prime
Can I buy a new seal? Mine leaks air.
A shopper on Jul 9, 2017
BEST ANSWER: We do not sell parts for the siphon. Sorry for any inconvenience. Cheers!
What size hose should I use on this? Would this product work? http://www.northernbrewer.com/5-16-id-siphon-hose
S C on Feb 19, 2016
BEST ANSWER: It works best with 5/16" ID siphon hose, but 3/8" will work as well.
Can it be sanitized with Alcohol 70%?
