How To Use FLEX - EK’s Brand New Leak Tester Tool | EK HOW TO

Making sure your liquid cooling loops are leak-free should be among your top priorities. Leaks can damage some of the expensive components in your build, so using a leak tester tool is a must when installing water-based cooling systems.
Enter FLEX!
FLEX is our brand new leak tester that will help you build perfect, leak-free loops. With FLEX, leak testing takes less than 15 minutes, which feels like a split second compared to the traditional 24-hour testing process.
Watch the video to learn how FLEX works and why it is the future of leak testing for liquid cooling systems. Feel free to comment below 👇 and don’t forget to share it with other water cooling enthusiasts who might need a FLEX in their life too.

Great, just days after I spent $60 on the old leak tester they come out with a new one for $30, I guess mine is rare vintage now

[@TheRedGhoul]

Holy hell why or where did you old one? I bought old one directly from EK when it came out for 30$. Going to buy the new one too tho, more handy in tighter places

[@SmolSir]

Maybe still on refund period?

[@stonyspeedxd131]

Same :(

[@zgu]

by vintage you mean leaky?

[@generalgrevous1984]

Had to send my old EK Leak Tester back so it's good to hear EK is redesigning and improving instead of profiting from old subpar tech like a great many companies. Update: just received new EK Leak Tester and it works really well. 😀👍

[@tyguenot1394]

My loop is done. First one and I used EK's components. Outstanding material and great video help. Thank you for going step by step through this with me. I made a few mistakes here and there, but after using 7 sticks of clear acrylic, I'm ready to pressure test. My last stick, my last bends, I creased the 2 90 degree bends, go figure, the last one. But I'm keeping it, after all, it wouldn't be mine if I didn't get to be reminded not to put the tubing so close to the heat gun 😂 I'll post pics. She's not perfect, but you all did such a great step by step guidance in your videos, I'm confident she'll hold the pressure. Pics to come, and thank you all so much for walking me through this.

Ekwb is by far the best brand

Aged like milk

[@rmp5s]

This is awesome. Give this crew a raise! I recently got my desktop done...went full Quantum, including the actively cooled backplate. I've been AMAZED by the performance. The mining temps on my 3090's memory dropped from ~110C all the way down to ~70C...that's NUTS!! Keep rocking, everyone!

[@zgu]

ngl I've become fond of this man

[@JeromeLaignel]

I ve done this, got a leak, checked all my fittings maybe 10 times a day was not able to find the leak. Then I hadded some water slight after giving up with the pump. I was able to find the leak and directly stopped the waterpump and could fix the leak like this. I guess I was lucky lucky it was one of the fittings that needed even more tightening

[@anshulmourya3044]

Thank you sir

[@dahawaiiansnipah4939]

All perfect I just got 1 in the mail just the other day.

[@chiyapet]

Hello! The manual suggested tested pressure "loop - 0.45 bar". Is the "loop" here referring to a completed loop? I.e. should I test my setup with 2 rads, 1 distribution plate, 1 gpu and 1 mobo block at 0.45 bar? Thanks!

[@alpinestars-wm8rv]

Hey guys, love your products. Speaking of which.. Where can I get my hands on the PC Mod Mat used in this video? Looks very classy, and I’ll be needing it for my new Corsair 1000D build. 👍

[@fairycat]

Thanks

[@smallz2495]

I think Freddy Mercury wanted to ride his bicycle, but I guess pumping it first would be a good idea as well. 🚴

[@limitedhangoutlive]

Can this be used to push water out of components for a flush?

[@Metalhead-4life]

Is that flex hose compatible with the Gen 1 EK leak tester? And if so do you sell it separately?

[@carlosjaques]

Yes, yes, it's all very well, but i finished my computer with the lian-li dk-05F computador table with a custom watercooling with all the EK fittings and tubes, i put 0.5bar on for 15 minutes, no leaks, put the liquid in and turned the computer on, so far so good. After 30 minutes of stress testing cpu and gpu the tube popped out of the gpu radiator with only 29 degrees of liquid temperature. I've only had 2 Corsair I-link fans burn out, Corsair has already said that the warranty doesn't work because it's not a manufacturing problem, now every time I turn on the computer I can't rest easy with this system of fitings.

[@Alphahydro]

This was pretty refreshing. I pumped my new build to 15 psi and it dropped to 14 after an hour. I've been anxious since.

[@skynetintex5878]

So, are you saying that after watching the video, you were OK with it dropping? I've had the same issue and nobody seemed to know. The video suggested that you only needed to measure for 15 mins max. I was measuring over 24 hours and couldn't work out why it was dropping a little bit.

[@Alphahydro]

@@skynetintex5878 I was fine, considering I pumped it to a pressure range the system won't ever operate in. Months later and no leaks. What was your target pressure for testing?

[@skynetintex5878]

@@Alphahydro I've literally just been pumping it up initially to 0.3 bar. It does seem to drop initially and then stabilise, which apparently is normal. I've also heard that you're not really supposed to measure over a long duration and that if you've not had a drop in pressure over 15 mins, that is sufficient.

[@user-yn3gc3sf5d]

Where can I find that assembly sheet. that one you have on the table.

[@petermuller5315]

Please update the pressure table shown in the video.

[@thecoolboy86gaming82]

Whens the nucleus vision 360 coming out? I need it

[@anshulmourya3044]

I order my components but i don't where I order the tubee

[@venividivici4253]

“Manometer - To measure my manliness” 🤣🤣🤣🤣🤣

[@damienlahoz]

Can this be used to get air out of a filled loop? I have stubborn air pocket in my CPU block that just keeps coming back.

[@Leon_Schuit]

Since it can only pump air into your system, I don't think it'll be of any help with that. You'll have to find a way to replace the air in your loop with coolant, in order to permanently get rid of it.

[@w3st80]

Good video, I think it's worth an upgrade from old leak tester

[@equinox8471]

can you use this for corsair x series components ?

[@EKWBofficial]

The EK-Leak Tester fits any components with G1/4 threads :)

[@allanwilmath8226]

I'm surprised that a company hasn't developed a vacuum fill system for custom loops. Basically you have a hand pump that pulls a vacuum with a valve you close, and then connected to a tee between the pump and system is another valuve you open with a tube you place in a bottle of coolant. Thus using vacuum to fill the loop like they do with advanced automobiles. Vacuum testing is also safer since you can't pull more than 1 atmosphere of vacuum, thus not exploding acetal/acrylic blocks.

[@EKWBofficial]

It's completely safe and easy to use our Leak Tester and you cannot damage the loop if you follow the instructions :) The pressure of up to 0.6 bar (marked with green on the scale) is nowhere near enough to damage our blocks but is exactly perfect for leak testing.

[@terencefdes2000]

1. Can this also be used to DRAIN OUT / FLUSH and Clean an EKWB dual loop (GPU+CPU) on a Thermaltake 900 The Tower System. 2. I wish to buy this latest version urgently - but it's just not available in India (older version is) HELP please

[@EKWBofficial]

The EK Leak Tester Flex's intended use is to check the systems/components for possible leaks and won't be of much help when draining the system. However, you should always check for leaks after cleaning the system. You can grab your own Leak Tester Flex here: www.ekwb.com/shop/ek-loop-leak-tester-flex

[@terencefdes2000]

@@EKWBofficial Thank you for your kind reply. I have ordered the latest EK Flex Loop Tester (Order No#200197875) & will be delivered on June 13th, 2022 at Mumbai - India for my Thermaltake 900 The Tower Snow Edition which has Dual EKWB Water Blocks and Radiators. BUT PLEASE HELP ME NOW ...... Would I STILL need to connect a *SPARE PSU* to Power up & Check the Blocks after Cleaning & Flushing is done? Is this an ABSOLUTE REQUIREMENT?

[@ErnestoMorin]

Right after I ordered the older one. 🙁

[@gotspeed_]

How do you release pressure once you are done with the test?

[@Lightscribe721]

Not making the flex tube available as a standalone purchase, backwards compatible with the old leak tester is a perfect example of why I go out of my way to avoid by EK products these days. Just a cartoonishly greedy company.

[@Kiserai90]

My leak tester leaks 🥲
