Damn, I was just about to order some of these...now I am in a fix as well, cause I need the concept to work, in terms of easier removal of hardware, but not at the cost of leaks.

My 2 sets of QDC VL3N's have been used and abused in the last year or so on my benching rig and are doing fine. Must be a recent issue with quality control. Best of luck brother.
Mine are over a year old and are having this issue, so I doubt it's a recent thing. I don't think it's all of them, but some definitely are having the issue.Quote:

Sometimes issues like this are mixed in the beginning since inventory has to roll over first. So if the changes were made a while ago, some people would get the new and some would get the old. Eventually, the old stock with the superior parts runs out and all that exists is the new revision. This would explain why some people have year old parts that exhibit the problem, and why others have old parts that do not.Quote:

I have had the same problem with a VL4N female QDC purchased in March 2011. 1 of the female QDC's that I bought is leaking as you guys have described it, i.e., after disconnecting the female QDC from the male side when filled with water, the female QDC leaks, drips and drizzles.
Additionally, I have had another problem that has not been mentioned previously: When I first took delivery of these three sets of VL4N's (3x Male & Female) one of the female VL4N plungers would not go down at all. It wouldn't budge, like it was frozen. I RMA'd that one, and the replacement one that I received had a lighter colored compression ring. The first ones i received all had what I would call the "black sparkle" finish, but the new one had the "shiny silver" finish. Thus, now I have 5 QDC's with dark compression rings and one oddball QDC with a shiny silver compression ring. To put it simply, it looks retarded. But w/e, i hid that one in the back. Not the worst problem, but annoying anyway. Still i think it shows a change in manufacturing has occurred at some time, or maybe several times. [Note: To avoid confusion, the female QDC that is now leaking is not the one with the funky silver-colored compression ring. It is one of the others with a dark sparkle compression ring.]
Yep, I got back the silver shiny compression ring on mine also and it does look odd having that with the black ones. It's somewhat annoying when you send one thing in and get something else in return unless it is an upgrade, which this is not.Quote:

If you all think Koolance should address the issue, please add your input to my thread in their forum ;)

I had to drain/refill all my loops this morning... I was really afraid... And guess what? 6 pairs of VL4N, and ALL of them are having that problem! The plunger doesn't retract fully, and water is leaking everywhere!
Sigh. I have alot of VL3N also, and they all seems to be ok. But ALL my VL4N are leaking...
I really regret buying those VL4N now, since the point was to make managing my loops easier, not harder! Really not happy. 6 on 6 are defective. Hope Koolance will do something. There is a real problem with those. :(
I also have this problem on female connectors, purchased early 2010.
Unfortunately I also just experienced the same thing this weekend. 1 of the 2 VL3N fittings in my graphics loop leaked after being connected for 2 months. Leaked on the first disconnet. Female does not retract.
I know Koolance will RMA them, but if the new ones do the same thing then what's the point?
That's exactly my problem. All my Koolance QDC are 2 months old, and all the VL4n are bad (6 pairs). So if I RMA them, i will get exactly the same leaking QDC. So what's the point.Quote:

Double post. Sorry. :)
We've found an issue after cutting open the bad fittings. The internal o-rings were a hair out of tolerance. This prevented the plunger from fully sealing when disconnected. Unfortunately, there's not a way to tell if a particular fitting is affected without disconnecting the male and female sides (a towel is recommended). Either the plunger surface won't sit flush with the inside, or if it's already installed, there could be continuous dripping.
We've screened our inventory and removed any other QDC's which exhibited the problem. Different styles of VL3N and VL4N fittings were affected, but the products aren't serialized so it's difficult to tell how recent the stock was.
If customers find they have VL3N or VL4N quick disconnects which leak when separated, please submit an RMA request (http://www.koolance.com/support/rma/). We'll need to know your part numbers, quantity, and invoice number/date. We'll take care of the shipping. If you've recently sent in QDC's for this problem, please contact our technical department (http://www.koolance.com/company/contact/) to obtain a refund on the original shipping and replacement fittings if needed.
We apologize for this issue and thank everyone for bringing it to our attention. O-rings are always a critical part and it's regrettable we didn't catch these when they arrived from our supplier.

^^This is why Koolance is awesome
:up:
Thank you Tim!!! :toast:
wow! TCB!!
Anyway we can get some sort of advance RMA on the ones that are already installed Tim? I really do not want to take my system down for a week while waiting on fittings.Quote:

+1 on this... I have several VL3N's of different types that are leaking and it would be more like 3 weeks for me in Australia!Quote:

Luckily I am in the middle of a rebuild and still waiting on some parts.
My only real problem is that I have $500 of new unused parts that are about to go in my rebuild and I dont know if they are defective or not!
