Quick Connect Question

Unread postAuthor: n-strike » Mon Jun 23, 2008 12:27 am

This might be a stupid question, but when you put air into these, does the air come back out, or is it kinda like a schrader valve and once air goes in, air doesn't come back out?

Yeah, pretty much like a schrader but quicker to work with.

There's no valve in them so air just comes back out. You'll need a ball valve to stop it.

The Quick Disconnect, which is the female fitting that attaches to Quick Connects have a valve in them so air only comes out when it is hooked up to a Quick Connect, so you can take it off and no air will come out.

Quick Disconnects look like this (the big gold fitting):

Edit: I have no idea which fitting you are talking about in the video.

So would the gold one act like a schrader? And the link I gave in my second post was off topic.

That's okay Ford, we all make mistakes sometimes. :)

this thing -->http://www.everyaircompressor.com/Campbell-Hausfeld-BC2468-CHP1254.html is a male quickconnect fitting - it does not act like a shrader valve because it's hollow inside

what you are looking for is a female quickconnect fitting.. it's what you plug this http://www.everyaircompressor.com/Campb ... P1254.html into. When it's disconected it stops air form getting out

EDIT
damn - I have to write faster

Alright, awesome. So I could substitute a schrader for that and put it on my gun?

The big gold fitting acts like a schrader.

I always use 'Quick Connect' to describe the male fitting with the hose barb type adapter, they come in gold or silver btw.

I use 'Quick Disconnect' to describe the female fitting that connects to a 'Quick Connect'. They also come in gold or silver.

When I say 'male' or 'female' fitting, I don't mean the threads, but what it looks like on the opposite end.

Yep, I understand about the male and female. And a little off topic, but where can I find schraders? I only find tire valves which are schraders, just rubber. They stick out of my gun to much, and since they're rubber, they bend. So yea, where can I find schraders?

the male qc will not hold air in a chamber a female qc is the one with the valve in it.

as for the second.....I would not recommend that stuff....it comes apart a little harder than it goes together. a comstant psi of 100-120 might be ok for a while but any more and it could stretch the fittings and blow apart.

I find schraders in the brass fittings area at my local "Ace Hardware". You may also find them in the plumbing tools area, they use them when they pressure test a pipe.

I'm only bringing it to maybe 80-100 PSI, so I'm guessing it would be okay.

Have a look around McMaster, they have almost everything you'll ever need in this hobby:
http://www.mcmaster.com/

You can't link result pages from McMaster so you have to search the product code, so you'll probably want something like this:
8063K38 (copy and paste into the search tool on the McMaster site)

I have used a few of them before, they're perfect.

Okay, thanks MrCrowley. And I thought you were trying to go on MSN everyday...:wink:

I say I DON'T want a flexible cannon, and I didn't say cannon, I said valve.

How come my signature is not showing up?
