TSC QDs for air lines

Anybody have a problem with Zinc plated steel ,female air couplers fitting the male that fits brass ones. I bought a couple today and they don't fit. I had this problem years ago and don't remember the material type, or if I bought them from TSC or HF.

Miked them and the diameter of the hole is slightly smaller than it needs to be. I guess I could grind off my males but I shouldn't have to. Too many for one thing, they might not fit my brass receivers for another, and I shouldn't have to put up with that. Thought I was going to hook up my new air compressor I got from there today but I guess not.

Comments appreciated.

And Happy "Gobble" day.

here are several fitting types and some are only small differences, but won't interchange. Then there is the so called universal ones. A pain.
 
I got some like that from Lowes several years ago.

I didn't use them, didn't want to get something started that would come back to haunt me later.

Intended to take them back, ran across them the other day, still in the package, need to throw them out.
 
Yes, I had same issue with the cheapos, got rid of all of them and bought Miltons, they last many times longer. Sold at Rural King.
 
Any way to know ahead of time other than taking a male with you and tearing open the packages...obviously a store nono?

Take the male with you and ask a clerk to match it.

I started collecting quite a collection of mis-matched fittings, so a couple years back I bought a bunch of Milton brass fittings; not the cheapest, but also not the most expensive. It's nice to have everything playing well together now.

Started a new "junk box" with the old fittings.
 
I made the mistake of telling the sales girl my male part was too big and now she won't leave me alone! :)
 
What did we do before the internet besides without. Got to digging into things and it seems there are 3 popular types of connectors of the sort that most of us STOs (I guess) use: Automotive, Industrial, a Universal and a couple others. Seems I use Industrial males and I bought Automotive females which was my problem. Diameter is slightly smaller. What I (didn't know) I wanted was the I/M connector which is the Industrial Milton.

Seems some of my older female couplers are universal and they have a sloppy fit. I find that the connector is marked with the size and the marking, T for Automotive, IM for industrial, and U for universal.

So I will shop wiser next time. Maybe this will help you shop wiser too. HF has great prices on brass couplings.
 
One of our local stores has a selection of all of their air fittings mounted on a display so you can try yours out and get the right one. I also have some that "almost fit, but don't". Now I take one with me when I need a new one.
 
Many different styles of air line fittings even in the same size.

Like Foster M style fittings myself and they work good with the Prevost Couplers that I use.

I can get both the male and female couplers from NAPA for about $1 each. So I usually 10 of each whenever I buy them. That way I know that they will work on just about any air toll I have.
 
Recently run into another not problem but difference. On female ends I bought at discount store of some type there was only 1/2 as many of the retainer balls used to hold male fitting. Fit just fine but I,ll bet they wear out soon as well as wearing male 1/2's
 
1 more vote for the blue colored Prevost quick connect\release couplers.

I am slowly changing all my regular Milton style connectors out at home and we have been running them at work for the last 5 or 6 years without a failure. Heavy use environment and they perform well under abuse.

I have also run into the "almost right" fitting couplers and plugs over the years. I trust Milton and more recently Prevost for consistent quality.

Seems there are about as many different styles of air couplers as there are hydraulic couplers, with both many look real close but do not fit.

I have a box full of each that do not fit anything I have or use.

When I remember I bring along the boxes when visiting a friend or neighbor, then we dig through each others collections.

I usually get rid of a few they can use and gain a few I can use.

A few of the oddball ones I have I have used to make adapters for things that are rarely ever used and are not worth spending the time or money to convert to the style fittings I use.

First off, looking for tight connectors that dont leak when the impact is laid on the floor or at an odd angel. SO far have not found any.

second, the harbor freight "males" snap off as they are cut too thin so they dont last long. Slowly moving back to all milton's till something better comes along.
 
I have a couple different types and to tell the truth the brass HF ones I have had only one bad female connector. The worst thing you can do is drop them on the cement floor or in the dirt. Sand soil like I have is deadly! Made a little adapter jig years ago to true male fittings. Goes in a drill press. You screw the fitting on, go with the low speed, and then take a fine file and gently true the face and surfaces. Just a little touch does them pretty good. Very little air lose after that trim job. Have half a dozen Milton air pressure gauges. Like $18.oo ea. at car shows. 0-160 0-60 0-15 pounds. Just be carefull with that 15 pound gauge, easy to blow up. Great for lawn tractors.
 
I usually buy brass females too from HF and as I type half a dozen are on order from them, the I/M ?". Just happened to be at TSC yesterday and HF was in the next town and I didn't feel like driving over there. Course ordering online means TX sales tax and shipping but that's still cheaper than a drive over there and fighting traffic and all.

I have a few Snap on 3/8 air ratchets that came with about an 18 inch whip hose on them.
Never a leak at the air couplers as there is no coupler side load where the hose fitting meets the tool.
 
I don't know it's a "whip hose" or not but I bought a couple of approximately 6' stretched out, yellow, coiled, springy, thin plastic hoses with a swivel on
one end for connecting to a tool in a workbench-assembly line environment. Had them for years and never had a leak. Kinking a hose every once in
awhile didn't result in a rupture. I was impressed.
 
After fooling around with cheaper (and sometimes more expensive) brands of air line fittings I only buy Milton.

Personally I like the A type.
