used valve question

milldoggy · Oct 25, 2011

All,
I have a chance to get a few 3 piece balls valves cheap, but they are used and came from a chemical plant. Not sure what chemical though. Should I just pass? I am not worried about the stainless, just the non metal seals. Thoughts?

depends on how cheap, and if you can get replacement seals. if they were really cheap, i might just grab them anyway.

Around 5 each. Any ideas where to find the replacement seals? They typically are teflon, does that asorb chemicals?

Bump, any more thoughts out there?

At that price? Go for it and replace the seals. Better yet, give me the contact info and I'll take them so you don't have to worry...

I doubt the teflon would absorb enough to worry about. I'd take them apart and soak them in 200F oxiclean for an hour, rinse and go for it.

Bobby... aren't you selling them now? Shoulda told him to pass...

milldoggy · Oct 26, 2011

Thanks guys. Bobby do you sell just the seals?

If I ever sell out a fellow homebrewer for a small profit, kick me in the nuts.

Nope, I don't have a source for the seals but I really wouldn't worry too much. PTFE is not that absorbent and the amount of exposure is very small anyway.

Got them in today. Turns out they are jamesbury CF8M valves. They pretty darn heavy! Not sure if they are full port or not, but either way, I will use them on my herms which it 1/2 od, so does not really matter. Got 3 for 15.95 shipped.

I've never seen a 3-piece that wasn't full port.

Just checked, there is an edge in the valve after the thread, but it is the thickness of the wall of a nipple. They weigh 2 lbs. Happy with my find.
