Sad to say I'd be ponying up to maintain the awesomeness. Do you have a supplier that you get 'em from?
Need to go in my "as-if" tractor bookmark folder....

If I knew where to get them I would do that.

Email returned. Thanks!

For the sake of the discussion, this is what I had in mind.
I am certainly not locked into this design, but it'd work. Maybe there is a less fitting intensive design. I've seen those air manifolds (http://ecx.images-amazon.com/images/I/51avnKHPgDL._SX342_.jpg) but it's a 3-up with a spot for a valve, not a 4-up. Plus I dunno about room for the other fitting half.

This is 3/8 fittings and nipples, probably just from Home Depot. 1" nipples appear to be plenty large and give room for the mating fittings.

aeblank, How did you make out with your Manifold idea? I've used the heck out of my Small manifold idea ( THREAD #9) and I'm happy with it. I can't imagine having to buy the Mates to that Italian connector for each implement. Although it is cool looking.
This must be cheaper IF you could buy one here in the States
QUICK-ON

My Kub. came with "Faster" brand fittings, they are a regular "ag" pattern available locally.
FWIW, I think that a lot of electricaly operated 3 function valves leak some past the sol.valve creating just enough pressure to make connection hard. It seems that a tablespoon or so of fluid that I see when using my little tool is all it takes to make it a not so quick connect :laughing:

Exactly what i suspect is happening too...

Dunno yet. Haven't used it. I finally built it though!
It wasn't too bad, cost wise. Maybe $40 or $50.
That's only a couple years to pay off, in frustration/hr. on re-assembly.

I did what I mentioned in my post (post #9 I think) I made a pressure release with extra connectors. The problem isn't with the tractor it's with the implement. If you try to reconnect when the temperature is hotter than when you disconnected.... It builds pressure in the lines. It's a problem with the 'new' Flush Face connectors (ISO16028). They are environmentally friendly, just not User friendly.

How well does this "tool" work? Would see that you still are having to compress the face of the coupler which is what's preventing the lines from connecting. If it works, then I'm building one, but these couplers arn't cheap!

Seems to me you could make a connector 'jack' out of a Vise-Grips hand clamp that would work like a bottle cork installer. The amount of movement is not very much. Get the couplers close and aligned, then squeeze it to press the male into the female joint. The mechanical advantage ought to be high enough to make the connection with hand grip force.

I'll start scrounging for just the right Vise-Grips. One of my welder clamps just started to talk to me. Once in a Blue Moon (that's twice a year), a hose line pulls out of my haybine for some unknown reason (hard turn maybe). If the header is raised, I have to drain the pressure off in order to reconnect. Problem will be "where is the darned thing when I need it".

I had flat faced ones on my skidsteer and I replaced them. They were hard to connect and then started leaking. I figure if they were going to leak I would reoplace them with the cheaper ones. That was several years ago and so far no leaks. Still cannot connect with machine running but a wood dowel and rag takes of that

If you install connect under pressure fittings on your machine, you won't have to deal with each implement. I have them on my CTL and no longer have any problems with any of my 9 hydraulic attachments.
