Coupler styles--why are there 2?

[Discount Hydraulic Hose]

I believe the "push to connect" reference was to the Agri standard coupler... which is a push to connect and pull to disconnect. No collar or ring to release. You just pull on the hose or fitting.

Can you tell me more about these? The standard Agricultural couplers I'm familiar with are the ISO 5675 couplers I linked to in my previous comment. Parker/Pioneer "4000 Series" are the best known examples of ISO 56875 couplers.

I am also aware that some manufacturers offer a mounting bracket which allows for easier (one hand?) connection and disconnection, but I am not very familiar with the operation of said brackets.

I see the confusion now. I went here to refresh my memory on the different standards: ISO 5675 Agricultural Hydraulic Quick Disconnects

I never paid much attention to it until now, but it looks like the "standard" is the mating of the male and female couplers... not necesary the operation. In other words, my Kubota has this standard (I buy the 8010-4 male -- which is the male pictured at the very top of the page) however the female coupler does not have a locking ring that must be pushed back to release. Mine you just push to connect and pull to disconnect.

I can take a picture tonight and post it.

Do you happen to have the break-away kit? That kits for the Pioneer couplers will allow you to insert the couplers, and pull away, with out you touching the sleeves. The bracket does all the work. Should you drive off with the hoses still attached, the bracket will pull the sleeves and release the hoses.

There is also the lever release couplers.

Some of the couplers also will allow one to either push or pull the sleeve.

On some of my couplers, you have to turn the sleeve and pull.

I see you guys found the break away bracket. They have been around a long time.

No break-away kit. My point was MY couplers do not have sleeves. You simply pull on the hose and they disconnect. (Actually, I prefer to pull on the male end so I am not pulling on the hose, however I said 'hose' to illustrate there is no sleeve to mess with.) Here is a pic of my rear remotes:

Here is a pic of mine, no collars either. The fittings are fastened directly to the valves, there is no bracket what so ever. You need to zoom in to get a better look.

Are you saying that to unplug, you pull the male coupling out. What keeps it locked in place? Is there a sleeve under the rubber part, or a release mechanism? What brand are they?

Do you have to push in first and then pull?

Mine are what come OEM for Mahindra QDs. I have to push first and then pull to disconnect mine. However mine work, it is all internal.

Yup, just pull on the male coupler. No push-first... just pull. It was new to me when I bought my tractor. I stared at it for an hour before I got on the net an did a search. Apparently they are fairly common. No sleeve under the rubber. That rubber you see is only the protective cover. I can pull that rubber off and there is only a groove where the rubber seats.

Mine say Parker on them. I can get the part number if you want. They accept the ag standard (ISO 5675 male couplers).

They snap into place, but they must lock somehow when fluid flows. When under operation, you can't pull them out.... however there is not a "pressure buildup issue" like the skid-steer couplers. (I guess there could be that issue since they lock under pressure, but my HTL has never caused that problem.)

There is a set of balls that snap into the detent of the male coupler. I think something internally locks the balls when fluid is flowing. I'm envisioning some sort of internal, fluid flow activated, collar/ring.

I do have a set of standard skid-steer couplers on my FEL remotes. Those of course have a collar.

If you have a part number for these, I would be curious to see it. I've been looking through my Parker catalog, and on their web site, and I can't find anything like these.
