This is what I'm looking at doing (thanks Joshua - "jkfrieke"), except with a dimpled coupling instead of the hex nut:

I like the idea of the silicon o-ring or washer between the outer edge of the coupling and a washer on the element itself though as well.

So, I took some pictures when I got home last night. The second picture shows how the OD of the O-ring is slightly smaller than the ID of the stainless washer. When compressed between the box and kettle, the washer prevents the O-ring from deforming.

Got a few pix last night. The first one shows the type of CPVC pipe to male pipe thread adapter that I pressed into the tapered stainless fitting. Then, I filled around it with JB Weld from the large end, and topped it off with a couple of stainless washers epoxied in. The next one shows the small end, with a short piece of 1/2 in. copper pipe pressed into the CPVC pipe end. It fit perfectly, I didn't even glue it. For the receiving end, I used a 2 in. ABS plastic pipe coupling, cut down in length. Topped that off with a very short piece of ABS pipe glued into a ABS pipe cap, with a hole drilled for the bolt.

For my keggle I drilled a 1 1/4 inch hole with a step bit then dimpled with a SS 1-1/4 to 1 weld reducer. I didn't need anything extra to keep it aligned. As long as you center everything as you tighten it down it will pull through straight. My element was able to screw all the way into the half coupling so I didn't need to chase the threads at all.
