I'm in the middle of plumbing the shop with copper and am almost to the point where I need to buy quick disconnects. The main line will be 3/4" and all the drops will be done in 1/2" copper except the blast cabinet which will be 3/4" with a flex hose. What I want to know is:

What style? (I was thinking universal for flexibility)

What manufacturer for quality?

Where to buy?

What size (3/8" 1/4" etc.)?

I would like to standardize as much as I can so I don't have to stop in the middle of a job to swap air fitting on hoses, I hate that. So if 1/4" will do, then all my hoses will be fitted with 1/4" fittings and if 3/8" then the the same will apply.

Thanks,
Tom

You could probably find all this online for a manufacturer. I remember there was an answer in the last one with some links let me try and find it.

Everyone I know uses whatever whater fitting they use at work.

I have benn using Milton 777(A style connector) since the 80s and never had a problem.

I work in an office. Air tools are only used when the boss get out of line :lol:

From my reading I decided to go with 1/4" Milton type V from Northern Tool. They seem to come highly recommended.

Man I hate when people just tell you to search It's not that hard to give the guy a ounce of advice. These comments shouldn't even exist at any forum as they help no one. Most air lines are 3/8 that take a 1/4" fitting so go with that. Also they make a 1/2 for your blaster. Don

I would ask you buddies what style they have and go from there.

I also use the Milton brand and have no complaints.

I have "M" style that seems to be the most common around here.

My fittings are mostly 1/4" style. My blast cabinet is also 1/4" fittings with 3/8" hose. The only thing I have that uses 3/8" fittings and 1/2" hose is the 1" impact gun.

I agree with Djd99 if you are going to post you can answer the question and then say that if you search you will be able to find a lot of additional information.

1/4 Millton type M is as close to standard you will get that is what I use for general use and most everyone has them. You should plumb it sow you can add duel disconnects (3/8 Millton type P, 1/2) when needing high volume (sand blasting, or high torque on your impact.

I have used many and the ones i like the most are the craftsman professional line I think they call them one handed & you can get them in a kit pretty cheap...lets see if i can find the link
ahhh http://www.craftsman.com/shc/s/p_10...ord=air+kit&prdNo=12&blockNo=12&blockType=L12

hey call it the Craftsman 16 pc. Pro Accessory Kit , they have it on sale once in a while for 24.99
the coil hose is "really nice" not cheap like most coil hoses & it comes with a 2 or 3 quick connects that are the style i was talking about...

These are the best I have found. I used the cheapies before and they wear out way too fast. Anything like this made from brass is a bad idea for hose couplers. The CEJN are not cheap, but they are well worth it. They don't leak and are easy to connect and disconnect.

I have all CEJN and am trying a few Oetiker as well (Swivel).

I have yet to find a good swivel that I like though.

As to the CEJN: I know they've got the Stainless line, but the basic 310 and 410 lines (industrial type) are brass with a nickel plate, I believe.

The brass is already starting to deform on my couplers. I believe because they're being tugged on quite a bit and it's a shop and the people using them (often) don't care like you do to take care of stuff.

Still, so far they've handled the abuse. But they are brass. Or at least the internal connecting portion of a CEJN is.

They're priced considerably lower on MSCDirect (in the USA). I'm not sure which you are looking at for US$66. On sale at MSC I paid between $20-something and the $30-something depending upon the model.

I have never paid that much for them. I am pretty sure the last one I got was the 1/2 barbed one, on my 1/2in line. It wasn't but around 20-25. It has been several years since I bought the 3/8s one, but I don't remember it being that expensive. Check your local hose and hydraulic shops for these. I buy mine at Imperial Supply in Huntsville. Anthony is awesome and will take care of you. Might call him to see what all he has and if he will ship them too you.

I could not tollerate leaking couplings. The Parkers that I use hold up well, but they seem a little harder to connect than the SwageLocks my buddy uses. Both brands are pricier than the Big Box Store brands. Greg.

It looks like Milton offers a similar coupler like the euro stuff. It also will accept M fittings. Seems like a good option, althought I have no experience with it. Anyone?

Do any of you use "T" style fittings? I got started using them a loong time ago, and they seem to work fine. No one here mentioned them, though...

I use the T style at work and at home. All of our shop air drops use T style Prevost connectors.

They work fine. I actually prefer them since I think the larger detent holds the connector in better.
