Element cover

Postby huntercg » Thu Jul 12, 2018 8:59 pm

Hi guys. Ive just got my keg back from a stainless place where I had a couple of threaded couplings welded on for the elements. I had planned on using a junction/ adaptable box as an element cover over the wiring as I saw it on somebodies build on the forum but I can’t find it now. Has anyone used a junction box as an element cover and if so how did you secure it to the keg?

Junction box might be the cheapest way but possibly not the best.

I would recommend a metal element cover for durability.

Thanks woodduck. I went and grabbed some 2” end caps. I drilled a 32mm hole in the end of them but I am having trouble getting the rubber gasket to seal on the socket that I have welded to my keg. I noticed that the elements macstill has in his post have silicon seals. Not sure if this is the issue but I have tried putting a heap of thread tape on the elements and it does help but they are still weaping. Thinking I might have to get an element from macstill. Anyone know when they will be open for business again or where else I can get a couple of elements?

What kind of sockets did you have welded on? What is the fitting on your element?

Could be the case you have a parallel socket thread and trying to screw a tapered element thread into it.

That configuration is typical for pipe fitting Nuddy. If it were the other way round, then there would be a problem. Most elements, regardless of where you buy them from come with the silicon o'ring (well, it's flat....). If yours doesn't have one, you can improvise with a high temperature (orange coloured) o-ring (ebay). That should fix your leaking problem. :handgestures-thumbupleft:

Thanks for the replies. Figured out I was overtightening them a bit too much and they were slightly out of shape in a couple of spots. Got them to seal finally and was able to give my still it’s first run.

I’ve got another question about my still build. I’m keen to use a 4” sight glass to the top of my keg so I can potentially see when the wash might be going to puke. Can I swap my 4” SS blank for a sight glass with the ferrule and triclamp or will this crack when I tighten it up?

Thanks Bluc. Do you use a gasket each side?

Gasket on the boiler side and wrap the edge of the glass with plumbers tape to help the clamp tighten up enough within too much friction on the glass. Just finger tight should be all you'll need. Better off with less pressure and giving it a test run, then tighten if needed.
