Keg/Kettle Conversion
Fortunately a brew bud did a conversion about a year ago & I have access to both a 1/2" drill & 7/8" drill bit. I'll check out the bargainfitting.com site, thanks.
But, I just got shot down this morning on putting my AG setup in the greenhouse.
Hell, I thought it would be a great place. Lots of moisture for the plants, & shit.
Problem here is that I don't have an attached or heated garage, & use filtered water to brew, & it's at the kitchen sink.
Guess I'll just have to figure out how to double my income & build the Brewski's Brewhaus addition on the house.

When you figure that out, let me know. Both with the permission for the Brewski Brewhous and the double income.
There was a recent post asking about using black rubber o-ring washers from the hardware store which did not get addressed. I notice that all the no-weld fittings tend to come with silicone type o-ring washers. Hence, I am wondering the same thing. Do the black rubber type o-ring washers impart taste or toxic issues to the wort? If there is a question, they are not worth the risk, but I am hoping for a more specific answer than that.

midwest has replacement o rings for the weldless fittings they sell. I think they are about $2.50. Probably would fit on any fitting.

I don't remember that post must have missed it.
The black rubber O-rings are probably not food grade. But what does that mean really these days with even "food grade" plastics generating scares of BPH etc etc.
I think it all comes down to a matter of dosage.
You probably don't want to steep 500 washers in your wort. But maybe one is OK.
Whether you taste it or not depends on that first run and if it imparts a noticable taste or not. I'd bet on subsequent runs it'll be less of an issue as fresh rubber has more potential to leach out rubberizing compounds than a used one. Regardless, the 100% silicon O rings eliminate these concerns.

All in the name of science and brewing.
You can thank me later.
well finally got the weldless valve setup working with no leaks, and even better, using only silicone orings. and teflon tape!! that was the difference maker.
here's my basic process, then i'll post some pics.
used step drill bit to drill a 13/16" hole per the instructions. this turned out to be slightly too small, so used the dremel to make it barely wider in diameter. could have just gone up to 7/8", but i was worried this would be too big and cause problems getting a good seal.
attached the coupling as tight as i could to the nipple. put a washer on the nipple, then a silicone oring. then put nipple through the hole, from the inside, so the threads were sticking outside the keg.
i then wrapped these threads a good 7 or 8 times with teflon tape, put on another silicone oring, and screwed the grooved, locknut down. i had to really tighten this down with pliers on the locknut and channel locks on the coupling inside the keg.
then the valve went on, tightened down with pliers/wrenches. then coated the threads of the barb with 4-5 wraps of teflon and tightened it into the open end of the valve.
it definitely took a little more fiddling and adjusting then i thought it would, but seems to be a perfect seal now. the main problem i had was not putting teflon on the nipple threads outside the keg, once i did that everything was pretty much solved.
thanks for the tips!!
hmm, noticed pictures aren't showing up. what's the best way to post pics?

I use photobucket, once uploaded into my album, I click the IMG link below it and it copies, then you can just paste it into your post. As you may have noticed I really enjoy this.
I dont use flickr at all, but it is probably very similar
is that the ball valve and bulkhead from bargain fittings? if so, how do you like it? I might order sometime...
yep, i ordered the set that came with bulkhead, ball valve, nipple, two washers(i only used one), two orings, locknut and barb. i am very satisfied with their set up so far. very heavy duty, and once i got it adjusted and not leaking, it's been working perfectly. shipping was on time and they had the best prices i found.
