Although it is logical.
Is this acronym recognized through the hyd world. I don't remember ever seeing it, or the one above.
The only reference I found pointed to the post above.

I made it up. As an engineer and scientist I do a lot of formal papers and reports. In general the use of excessive acronyms is frowned upon, but occasional use okay to avoid repetitions as long as you define it in context. In other words, I'm too lazy to keep typing those five words again.

Clumber's world and mine intersect, I guess. In my busness (military), we have a TLA (Three Letter Acronym) and FLA (Four Letter Acronym) for everything. To the uninitiated, our conversations appear to be in a foreign language.
It can be particularly annoying when going through tech manuals for new equipment. The standard is to define the acronym the first time that it is used, and then use the acronym by itself everywhere else. If you are skipping around in the book, sometimes it can be almost impossible to locate that "first time use".

I have both styles. I really do not notice a difference.

Laughs - just realized the "under pressure" ones are on my filter cart which is never under pressure when hooking up.

Folks, here is a note from Ken H. at Discount H... Hose.:
Patrick, I don't think flat-face couplers are the answer to your problem. They take more force to push together than the ag style couplers. The main difference, though, is that they push directly in, without requiring you to pull back a ring like the others do.
If you still want to buy the flat-face couplers, you can find them on our web site at http://www.discounthydraulichose.com...lers_s/155.htm
The connect-under-pressure couplers, as you will see, are much more expensive, and I also don't think they will address your problem.
One of my co-workers ran into a customer at a trade show who is making a tool which supposedly assists with this problem. I will try to get some information on that for you.

I got the impression from the forum that they are much easier connect. I guess I will have to buy some and try them.

I get it now. The ones that connect under pressure just push on and there is no locking ring to retract.
Even if they require more force to connect, the fact that they do not require the ring to be pulled back may be a plus.
Still, with the added cost, I would look at possibly moving the AUX PTO connections a bit forward in their sleeves on the FEL arms to give your fingers a bit of room, if possible (as someone else suggested) and always turn the tractor off and flip the AUX PTO lever a few times first, to see if that helps.
I do know that once in a while they can be stubborn and can only imagine it would be more difficult with reduced strength or arthritis in my hands. I just cringe at the thought of replacing all of those fittings.
Maybe just purchase one set and do one side of an implement to see if it makes a difference for you so you are not out a bunch of $$ if they don't.
I am interested in the tool that you mention.

Strange, I find mine easier to connect than Ag style. Laughs - I must have done something wrong.

The Parker 8200/9200 Series QD can be connected, with both sides under pressure.
Some of the others will connect up to 500 psi .
