Sanke Fermenter Prototypes

[haeffnkr]

Hello,

Thanks to you all I came up with my "coupler" design.
I will let you know how it works, this morning it was holding at 5 pounds.

Also - the first time I used the thermowell, I did not have to get tape to stick to the cold wet sides of the keg, It was worth the added expense to get the units from Bobby_M.
It was awesome.

Thanks again for all the tips and pics.

Comments welcome

How many PSI have people been getting when using the orings and/or the delrin compression fittings?

I have only seen about 8 psi, not sure if I missed the window and my yeast is done or if I have a leak at the compression fitting.

thanks Kevin

Since this app wont let me add photos to private msgs - here you go haff (sp)
The first is with the cap on, the second is with the cap off.
It is basically a spare piece of ss (hammered shut then silver soldered closed) I use a ss washer on the full bore compression top to my piece as a I never could hold any pressure for long term via the delrin or orings.

Hope this helps!

Here is the sanke setup with spunding valve, pressure gauge, safety valve, and gas connector.

This is fantastic! Great design, you must have thought of everything! I'm inspired, thanks!

Hi friends, sorry to bring up an old-ish thread but I'm looking for a bit of guidance. Let's say I plan to use a 1/2" OD SS racking cane. What I'm hearing is that a 1/2" compression fitting won't seal it under pressure, so people are replacing the compression ferrule with o-rings.

Is that right? I'd like to keep the racking cane adjustable at least until I know what my final height will be to minimize trub while racking.

Where did you hear that a nylon compression ferrule will not hold under pressure?

I didn't say nylon, but I assumed SS compression fittings would use SS ferrules, and I was basing my question on this post.

I'm putting together a parts list now and I'm actually going to use a 3/8" OD racking cane, with a 1/2" NPT cross at the keg and a 1/2" NPT ball valve on the end of the cane. But my question is the same - will the included ferrules with a standard 1/2" MPT x 3/8" bore compression fitting hold pressure even if I undo and redo the height of the cane at least once or twice? I would have guessed there was no problem, but I wanted to make sure based on that post I linked above.

Get Bobby's ss 1/2 cane with his bore through compression fitting and call it a day. Seals just fine, I push with gas and it works like a charm. Side note, Bobby, if you wanted to make a nut that fits on that that had some wings on it so I wouldn't have to use a wrench when racking...I would buy one!

You won't have any issue sealing if you use the regular parts from the compression fitting. You will however have a lot more trouble trying to slide the tubing through it. I'd reconnect the bored through compression fitting with o-rings as well.

If you buy the setup from me, or even just the bore through compression fittings, you have a choice of SS or Nylon Ferrule. The latter will seal just fine with light torque on the nut and will allow you to slide the cane to any depth over and over without hard setting SS ferrules. A pair of orings work the same way but you have to keep them well lubed to not destroy them when setting depths.

Got it, thanks for the advice!
