any one ever use these fluid connectors. They have rubber gaskets and work well just have to bore them out to a few thousands under and can be press fit to your pipe.

Aluminum, but none of it is exposed when the pipe it pressed all the way to the inner shoulder. The one end of the ss bit was worked just for my boiler but they could be just connectors. Pretty sure you can find these any where they sell large flexable water line. I got these for free though.

There called Chicago fittings. I have used them on the job for air and water service but never for that use.

Second the comment on rubber gaskets, but they should be easy to replace, let us know how they work!

Maybe I'm naive but the pressure cooker I used to use (presto brand) had a rubber gasket and I've made some tasty hooch with it am I going to die from rubber poisoning or get sick. I have done a cleaning run with them and they seemed unaffected I'm sure I can find a sub without looking too hard. Or maybe I will make rubber rum, uncle Jesse rubber mash, rubbing alcohol. :idea: Maybe the rubber challenge, one shot with rub and one without see if anyone can tell the difference.

They're actually called 1/4 turn or sexless whatever you prefer I like 1/4 turn better. Although chicago fittings does sell them.

I wouldn't sweat a rubber gasket on a potstil if it was me. And it is, i've had a rubber gasket at the base of my columns where it joins the boiler (pot and reflux) ever since i started. There's no degradation to the edpm and no sign of any damage to the hooch either.

Thanks for the input Punkin. I kinda figured they were ok to use but didn't wanna stir any shit by saying so. I've read a thread on EPDM a while back when I started 4 months ago and it calmed my nerves about using a little rub in places. And found that thes couplers are not cheap to buy 50+ US, but as I said they were free to me so what the hell.

I've had pretty much the same experience as Punkin, with black rubber pressure-cooker sealing rings (sorry, Harry, I could never get that fat silicone ring squzz in). Although I've never had a taste problem with them, over a period of years they do shrink a bit and harden a bit, so something must be happening to the rubber, but very slowly.

I may replace the sealing ring every 4 or 5 years.

Rubber degrades when left in ultra violet light, and that is hard to avoid.
