I got some of these from grainger, and they barely fit in my diptube. I broke 2 of them trying to shove them in the tube. broke into a bunch of little pieces. Then after my keg was empty i was a real pain trying to get them out. Tried the air compressor and that didnt work. I ended up shoving a piece of solid copper wire up there to get them out.

AWESOME!!!! I just went to Grainger and picked a couple up. I set up my keezer yesterday and was blowing foam and getting piss#d. These things kick ass! FYI these are the ones I got. http://www.grainger.com/Grainger/DEVCON-Epoxy-Mix-Nozzle-4TT44
I also ordered a pack of these http://www.grainger.com/Grainger/LOCTITE-Mix-Nozzle-3NVL6?Pid=search
The devcon one's are .240" or thereabouts. I put mine in the bottom of my dip tube. The end with the flat piece is a little wider so I put the other end in and it fits great.
day_trippr said:that might explain why some folks are having trouble getting mixers to fit their dip tubes. I got the loctite brand ones from my local grainger and they literally drop right in the tubes, no pushing required, so they're likely a bit skinnier than the devcon brand mixers...
Cheers!
I can't believe how long this thread is! Anyway... has anyone ever had trouble using these with Perlick faucets? I'm trying to do a little troubleshooting and just throwing that out there.
I guess im confused. You guys all use perlick taps or something similar right? I can see why you would need something if using a picnic tap, but if you are serving out of regular taps why not just buy more hose? its cheap.
I have 10' coiled sitting on top of each keg in my fridge and it came out perfect from the very first pour.
Not trying to be contrary, just trying to figure out your mission.
These things would work great in a Immersion CHiller or a HEX ..... breaks up the boundary layer on the inside of the tubing for better heat exchanges....
just my two cents.
Hey all - first post, just wanted to try to give back to the community... great thread, and thanks to the OP for the suggestion - works like a champ!
Here's the Delrin MSDS from DuPont.
I'm no chemical engineer, but looks to me like you shouldn't burn it, or use with "strong" acids or bases, or oxidizers.
The last part got me - might not want to hose the swizzle down with Star-San without a good rinse afterward... I like preserving the flavor of my beer, but preferably not with formaldehyde. I'm pretty sure Star-San is considered an oxidizer, but it's definitely an acid-based cleaner: StarSan Tech Sheet. Whether or not it's "strong" enough in diluted form to affect the swizzle is anyone's guess.
With that said, I'll give them a good wash and rinse with bottled distilled water, then pop them in tonight to see how it goes... but I think I'll take my chances avoiding the StarSan...
Interesting data, but at 1 to 256 dilution (1oz to 5 gallons) and 30 seconds contact time I'm not all that concerned.
Not to denigrate what you're doing... it sounds like you're in a CSI lab, pretty high tech stuff. Do you think beer is acidic enough to break down delrin? That might be more concerning given the contact time is weeks/months and that it's actually consumed - unlike the starsan.

And as an FYI, I'm already using these mixers, but I'd like to know what's going on because there are stainless steel products out there claiming to do similar things.
Intriguing. Care to share? How about a pointer?
Cheers!
I have two of the swizzles as a second attempt. They did not work so well the first time because my beer was over carbonated. Now that I let this one slowly carbonate, they work like a charm!
Do you guys reuse these from batch to batch?
I got some of these this week and think they're awesome. They make so much sense it's surprising you don't see a product on homebrew sites to do this. Likewise, all over the forums people talk about longer hoses... This is better!
Oh man, you had to go get scientific on us. I reduced your equation:
2 mixers + some bit of hose = sort of slow but good nuff pour!

They do work well. However, there definitely is some interaction between the beer and the plastic, as over months/years they become quite brittle.
Fortunately I have a friend in the metalworking industry who made me essentially the same thing, but made of 316 stainless. They work awesome and will last forever.
Unfortunately, it's not economically viable to manufacture and sell them. They'd have to retail for around $14.
