Tool for hydraulic coupling

[Tony H]

I just put this together. I probably only needed one connector or the other to relieve the pressure in the attachment but I figure I will attach both connectors to this immediately after taking off the tractor. I will open the Valve into a cup just before reattaching. If noting else it will keep my connectors clean.
I'll still be looking to make that German HOLP tool so I'm not losing a bit of fluid every time.

I've read hundreds of posts about people trying to couple their hydraulics, but can't. This looks like the perfect tool!!
Hope it's available here soon. (or, do you know where to get one?)

Tne perfect tool is a brain, Bleed some fluid into a catch container when you decouple.

Obviously you can loosen connectors BUT Many of us feel that walking around with wrenches to make a drippy mess of our connectors,hoses and machine is not the right way. If opening connections was the correct method, they wouldn't the need to even have connectors. We are looking for a way to cleanly compensate for this Pressure issue, without sacrificing a whiskey Jigger of fluid every time.

Theres no pressure when you disconnect. Bleed immediately into catch container by depressing the ball or pin. No tool required. Saved fluid can be readdsd or used otherwise where needed.

I have some concerns about this setup. In the photo, you have taken a pair of hydraulic quick couplers rated for about 4,000 to 5,000 PSI and connected them to a brass tee that is probably rated for about 1,000 to 1,200 psi and a brass drain cock rated for maybe 30 psi.

You may bet better off purchasing one or more couplers for your attachment that are designed to connect under pressure.

I think you misunderstand what that is.

That is a adapter to add to an attachment to bleed off pressure caused by heat buildup.

Even those QD's that connect under pressure so not connect so well.

Also, some connect under some pressure to about 500 psi.

Some say they connect under full pressure.

I went to attach the top cylinder to the quick attach this spring and one hose went on fine, the other was a no go. I finally unscrewed the quick attach part, slid that into place and then screwed the hose back on to that. These pliers above look useful.
