Quick Disconnect Coupler Wisdom Needed - Size / Type

[2fast916]

Depends on where one sources them I guess.

I replaced all of the ag style couplers I had on my equipment with SS/FF QD's from these guys for pretty cheap (no affiliation or remuneration, just a satisfied customer):

Flush Face Coupler

They're a China product ... but I find that in terms of hydraulic fittings, that's what I'm getting from other places as well ... including my local hydraulic shop.

Some time has passed, since I started this thread and thought I would just update everyone on my findings / progress. First off, thanks to everyone who responded!!!

On my Kubota B2650, all the fittings on the Backhoe and 3rd Function Connections are all 3/8" and the four Loader connections are 1/4".

Since the Ag (Parker) seemed to be the most common for tractor related implements in the U.S., my first decision was to convert the 3rd Function QD’s to Ag. So I ordered a set from Discount Hydraulics and installed both the Male & Female. After installation, the Female worked great but, I could not get the Male to stop leaking at the “ball.” I tried to exercise it repeatedly by plugging into my grapple’s Female but, I just could not get it to stop dripping. I should also add, that it leaked more when the tractor was running but, also leaked (more slowly albeit) when the tractor was shut down.

The saga continues…and I was caught by curiosity…

Since I’ve never seen a Flush Face SS QD in person, I decided to order a set from Discount Hydraulics to see and potentially use. Once I had them in hand, I loved the design much better than any of the other three types. They seemed much more resistant to collecting and/or cleaning from dirt, etc and I really liked how you could turn the Female QD so, it could not disconnect on the fly. Long story short, I installed the Flush Face QD’s and am completely hooked on their design!!! After a connecting once or twice, it also became very clear what was meant by their “no drip” design…you get hardly a drop of hydraulic fluid on your hands, tractor, ground, etc. when they are disconnected. They are expensive but, it’s a one-time cost that I’m willing to incur…to make my life more enjoyable in the long run.

To date, I’ve only changed the 3rd Function QD’s and my grapple but, have on hand enough couplers to change all my remaining QD’s, including making an adapter between Ag & FF (addresses my initial concern to standardize between the two tractors), and having one set on hand as a spare if issues arise or if I purchase a new implement.

Thought everyone might like to know what I did with all the useful info provided…thanks again!!!

This is fairly typical from what I understand.

My thoughts as well :thumbsup:

If you check various manufacturer's websites you'll find that the fluid loss per connect/disconnect is usually rated in thousandths of a milliliter ... or some similar miniscule measurement in cc's ...

They are expensive but, it's a one-time cost that I'm willing to incur ... to make my life more enjoyable in the long run.

Actually, they really aren't (that expensive) ... depending on where you source them.

If you check the link I previously provided you'll see that they are available from that source for around $11 (1/4") to $15 (3/8") per set ...

That's a set of two ... one male and one female ...

That is crazy cheap. My supplier, as well as DHH is 3-4 times that price per set. I don't know how they are selling them for that. :confused3:

Yup ... that's what I thought ...

I spent around $200 awhile back to replace everything I had with the flush face units.

Unfortunately, I made an error and ordered too many 3/8" and not enough 1/4" ... fortunately however, shortly after I did it, a local TBN friend was looking to replace some of his AG style that were leaking and I got rid of the 4 extra sets of 3/8" I had.

Need to order some more 1/4" to replace them tonight or tomorrow ... they have an additional 15% off "special" going until the end of April

Who ... the guys I inked ... or your supplier and DHH ?
