Leaking quick couplers

CalG · Apr 15, 2015

I purchased a selection of components from one of the commercial members of this forum , that I might add a three spool loader valve in line with the aux hydraulics on my Hurlimann.

The install went just fine, lots of tubing bending and fitting fitting ;-) Everything works very nicely with one exception.

The 1/2" quick couples leak!
At first I thought it was any of the many threaded connections on the spool valve, (the valve it's self is ORB) but I put a paper towel around the connector, and sure enough.. it was the quick couple it's self doing the leaking.

I swapped to a second piece that I had purchased, (always buy extra and save shipping fees ;-) the leakage is reduced, but still drips down the valve mount etc.... Annoying!

So the couplings were new, and still leak. Will new o-rings fix them? Or are they just inadequate? There is a degree of flex associated with the full travel of the loader arms, but there are a pair of hoses and couplings following the same path, and only one leaks.

Or should I just bite the bullet an go buy "name brand" from the local hydraulics shop.

Sometimes, a good value seems like no value at all.

Contact the seller and discuss/resolve.

I'm not none to make an issue over an o-ring.

If it does not work properly straight out of the box why wouldn't you mention it?

Really? Then why bother asking if it's an o-ring issue, or something else? And why mention it's someone who advertises/sells on TBN?:confused2:

If this vendor is selling inferior cheaply made products, then they need to hear about it so they have the opportunity to make it right for you. You shouldn't have to "fix" a new product that they sold to you.

Put a little silicone grease on the o-rings.

Leaky quick connectors generally have cracked O-rings as the main culprit.
Can be as simple as a grain of sand or a tiny nick.

That's easy to fix, just install a new o-ring!

Naturally we assume tape or thread dope was used when installing.

Well, It appears that no one maker has the market cornered on "leakers"

I should have done a more thorough search. This is the type of information I was looking for.

If only one could "just pick up and o-ring " at the grocery store. Even the auto parts stores around here are less than useful. No "tractor supplies" within 20 miles. Unless you count TSC, and I don't!

Convert them all to skidsteer/flushface couplers - probably as cheap as the various other ISO types you can source - and it's a design that meant to minimize all the dripping and drooling:

A year ago I would have had to agree with you. Had them on my loader 3rd function since new. I never had a problem connecting them and could not understand why others did. Then, out of the blue, they started being a pain to connect, though nothing has been changed. Now I'm seriously considering switching to the Faster push-pull like is on the rear.

Anyone who owns tractors and does their own work on things, it is a worthwhile investment to buy a few o-ring assortment kits. I like to keep a 3/32" set and a 1/8" set. I have found that covers most everything on my tractor and backhoe. Weather it would work in couplers or not, i dont know cause I have never replaced one of them. Those o-ring kits are pretty cheap.

CalG · Apr 20, 2015

I've got a set of o-rings in a handi see through divider box. It has two sizes.. too small, and too big,,, ;-)

I must of used the Goldilocks sized ones years ago. ;-) Plus, A look at the sets sold at the FLAPS they are all made in China, and I just have this thing that tells me they are not the "best that money can buy".

LD1 · Apr 20, 2015

They would go perfect with the couplings made in china.

Not sure where my sets are made from, but they werent expensive so my guess is china. Never had an issue. Its just an o-ring, not a swiss watch with a hundred moving parts.

Yes but you see Chinese O rings are made from recycled chewing gum scraped from the streets of shanghai. They have people just for that!

Well, IF that were true, the o-ring in the coupling should be leak tight.

Alas, Reality does not work that way...;-)

Slow leaks are some of the most anoying things there are. :irked::irked::irked::irked::irked::thumbdown:

Topher265 · Apr 20, 2015

So where is a good place to get some of these assortment kits? I just noticed a leak on one of my accessory hydro couplers on my JD F935.

J_J · Apr 20, 2015

I would recommend the factory o-ring kits for the specific QD.

Maybe you think you know the size and type material, but I bet you are not sure.

Oh, it look right, lets use that black rubber band.

It is just to easy to shortcut I guess.
