Avoid spills with the EK Quick Disconnect Coupling connectors

Have you ever built a custom liquid-cooling system, gerbils? If you have, you know that the stellar performance and sublime silence of such a setup tend to come at a great cost of effort and fuss, particularly when it comes time to clean the machine. Now, EK might have a way to ease some of that hassle with its EK-QDC connectors.

QDC stands for "Quick Disconnect Coupling", and it's essentially a hose coupling that automatically seals itself when it is disconnected. The idea is that you can use EK-QDCs in your loop to prevent from having to unscrew, seal, and re-screw your fittings every time you take the system apart. The connector comes with 10-mm barb fittings on both ends. We've seen these fittings before as part of EK's closed-loop offerings, but this is the first time the company has offered them separately.

EK says the couplings are "medical grade," and notes that they are manufactured by Colder Products Company (CPC). That company has a long history of making products for the medical, industrial, and food industries. It's actually a little surprising that it's taken this long for someone to bring CPC's wares into the custom PC market. EK is selling the Quick Disconnect Couplings for $40.25 each at its web shop.

      That’s a beauty! What sort of wattages are you seeing through the lamps?

        They are 450 watt a piece and six of them in total.

          Yeah, no mucking around there!

My last loop went maintenance free for six years and all of the components look basically like the day they went in.

    “Medical grade” markup is right.

    I’ve had a single Koolance QD quick disconnect coupling at the lowest point of my loop for easier draining for the past 5 years with nary a leak or issue. Price was about $25. To me, they are aesthetically more pleasing as they were metal instead of plastic. Apparently the black ones had some corrosion issues, but I haven’t had an issue with the silver ones.

    Pretty sure that most people that need these (custom loop) already knew where to find them. On the other hand it’s only a good thing that EKs marketing will ensure that more people know about them. Pricey but oh so convenient!

    These can be found much cheaper (along with cheaper alternatives) at usplastics: [url<]http://usplastics.com/search/default.aspx?it=item&keyword=quick%20disconnect[/url<]

      Zoro tools is a few bucks cheaper. Can’t be bothered to check how shipping factors though. 🙂

      The former occupant of my desk at work left a copy of CPC’s catalog.
      P/N’s for anyone interested:
      NS6D17006 is the coupling body
      NS6d22006 is the coupling insert

        So basically EK’s charging the same price as everyone else? Because I see $32.99 on their site for this. Seems that’s very close, maybe even slightly cheaper, than buying these parts from another source. Maybe tax and shipping costs will net you a dollar one way or another.

          Yeah, pretty much.

    at $80.50 for the bare minimum of two, and more likely $161 for the likely scenario of four, I’m not surprised it has taken this long for someone to bring these to market.

    My Camelbak hydration pack has one of these things installed and you get one free with every $20 hydration bladder, despite the lion’s share of the cost going on the bladder itself, the fill cap, and the bite valve. The little quick-disconnect hose is like a $2 part, tops.

      You should write a letter to EK’s competitors explaining this opportunity they’re missing out on. Please share the response you get back.

      But yours aren’t “medical grade”…

          Those don’t look like they have the shutoff valves in them, so while they’ll work, one would need to be careful to catch the coolant that’ll drain out. Also, for anyone shopping: the EK units are for a 3/8″ ID (9.8mm).

            There are different models and sizes available. I tend to use the single direction shutoffs on my bike as my fuel flow is gated by other components. Shutoff on the tank end solves that issue, the fuel filter on the other side really only flows one way and I keep a capped plug to pop on there if the line will be disco’d for any length of time.

        Mine have to be food grade by law, I’m not sure anyone’s planning on buying these from EK to hook up to their dialysis machine tbh.

      You re-brand CPC stuff, you will pay for it. They’re food/medical-grade, which gives them license to do whatever they like.

      Koolance have had these for years – the older ones were a bit restrictive but the two newest revisions (3 and 4?) are good. I got two pair of 3/8″ with compression fittings for $70US about a year ago. Bitspower/Barrow now do them as well, at around $20AU each – cheap as chips.

      EKs own Predators had these incorporated.
