Default Quick disconnects

I've had a jaundiced view of these for a long time - which probably means it's wrong. Now I'm thinking of QD's instead of permanent plumbing for my connections using reinforced silicon hose from the pump to wherever. Gotta be much better for disassembly and cleaning. Is there a "best for the buck" QD that doesn't leak? If so - can you tell me where to get it?

I'm also on the hunt for some good Quick Disconnects. Stainless ones are pretty expensive (same price as tri-clovers it seems) and I found some brass stuff from McMaster Carr but they only say AIR rated. I called and they said they only rate it for air and can't comment on liquid uses. The price is nice and they are a push-in lock (one handed use) WITH a flow stopper.

Anyone used these and feel they are safe for brewing?

Here are two pieces

That's what most here use when using the QD's from McMaster.

Thanks for the confirmation.
Guess the one's I'm looking at would work but a little bit more expensive since I'm looking for 1/2" ID all the way through. That way no grain clogging on mash recirculation etc. I'm drawing out all the different connectors so I understand what I want my brewing rig to look like.

For a system set up using the McMaster-Carr brass quick disconnects, please take a look at my system: http://www.homebrewtalk.com/f51/brew...-today-117290/

Another option that looks very good are cam-lock fittings.

Here s a good site to get them from: http://proflowdynamics.reachlocal.co..._id=3002805091

I got a bunch of brass disconnects from Plastic Process Equipment for dirt cheap. They are straight-through 1/2" NPT, and cost less than the 3/8" ones from McMaster that are so popular. They also sell stainless ones that are interchangeable.

I think the female couplers were $6 and the male nipples were $2.25 each.

For my money, the tri-clovers are the way to go.

Yea, the cost a bit more, but you don't need to buy them all at once. I'm only using one right now. In a month or two I'll scrape up the cash for another. Hopefully, by year's end I'll have all I need.

I can't seem to find the SS couplers in that catalog. Can you give me a page number?

It is the same page as the brass ones. They don't show pictures of the stainless version, though. Stainless part numbers and prices are right beside those for the brass versions.
