I just got back from the Depot, and I found a slightly different solution using similar parts. It takes a little more fab work but it solves the problem of being able to rip the PVC away from the element. I'll post a thread with pictures as soon as I can.

Sounds good, I'm halfway decided in either using the junction box or pemanent PVC solution...perhaps this is the in-between solution. Looking forward to seeing this solution.

This is pretty much the same thing I have, except that I used a straight piece of PVC instead of an elbow. I didn't pot the connections inside with epoxy, but I sealed the outside well.

It's pretty solid. I can tug the keg around by the cable and things stay in place perfectly.

Edit: I tried first sealing with silicon, but the connection wasn't stable. It broke free and was a hazard. I re-did the sealing with JB Weld and it's like a rock now.

And I'll also sand the elbow smooth and spray it with some of that sweet hammered metal paint before final assembly.

PROST!
I also wanted to avoid the electrical box on the keg, but it was because the rubber coated keg made it much more difficult to mount the box than a standard keg.
Even if you pot the connections, the pvc elbow was so cheap, you can replace it at will much cheaper than the box setup.
During my last visit to lowes, I saw something that might be useful. A baseboard electric heat thermostat. It says no limits on temp, and it will easily switch my 1500 watt 120v element. I will have to lay down the cash to see if it will work, but it might be a low cost solution to heat control with the electric elements.

I guess that depends on how many times you anticipate replacing your elements. I paid $11/each for my waterproof boxes, and they don't need to be replaced if you have to replace the element. If you have to spend more than $5 to replace the elbow, buy new epoxy/JB weld, and new wire, then it might be more cost effective to go with the boxes (if you have to replace the elements 2 or more times in the lifetime of your rig). Otherwise, yeah, it's cheaper to go with the PVC and epoxy route.

I see what you are saying. The box is a good system, but for me I always seem to have sealant around (own a house), made my cord plenty long to cut off and start again, the elbow is 97¢, and this is in my hlt so I am thinking it will last awhile. Just tryin to get what worked for me out there.
I only used a small bead of silicone around the element base, so most of it could be re-used. for those that pot the whole thing in epoxy/jbweld it might be that the replace the whole setup when they replace the element.

to each their own. that is the beauty of this hobby. Ingenuity!

Well, right, but my comment was directed towards your words that I quoted above, not which method is better. I agree that different methods and desings will work for different people, and that is indeed one great thing about this hobby. Just keep in mind I wasn't criticizing your method/design, I was questioning the financial reasoning in the quoted text. You've got a method that should work well, with a reasonable initial investment, good job my friend!

TB

EDIT: note that I'm not trying to discourage you, or anyone thinking of using this method.
