EK Releases Liquid Cooling Leak Tester
EK is releasing the EK-Leak Tester. A fast and safe way of testing for possible leaks in your liquid cooling loop. While traditional leak testing works, it requires hours before very small leaks are detected and then things can get messy. The EK-Leak Tester does the job way better!
The main body is a solid piece of CNC machined aluminum. One end is fitted with a revolvable male G1/4″ connection port so it can be directly screwed onto any standard port in your liquid cooling loop. The gauge is custom made for liquid cooling loop testing purposes, which clearly marks the safe pressure for testing. The other side of the tester is hooked up with a valve that will make sure no air is escaping through the tester unit. The small pump for pressurizing the loop is also included. However, for a maximum safety effect, EK suggests reaching a pressure you want for testing and leaving the tester on for at least 15 minutes. If no pressure drop occurs and the gauge remains on the same spot, you’re good to go.
In order to prevent damage of your liquid cooling loop, keep the pressure in the predefined zone only, as marked on the gauge. Please read the user manual before using the EK-Leak Tester!
The EK-Leak Tester is assembled in Slovenia, Europe and it is readily available for purchase through the EK Webshop and Partner Reseller Network. In the table below, you can see the manufacturer suggested retail price (MSRP) with VAT included.
EK-Leak tester costs 34.90€

Cha'Ching! Bought one as well. Just the thought of not having to run the system for more than 24hrs or so is a dream come true.
Sitting there like a zombie and eyeing every part of the system you've got paper towels ladened with.
Disclaimer states clearly that it is in spec for EK parts only....only makes sense I guess.
This will definitely help with the upgrade to TR2 or whatever AMD is going to name their next ThreadRipper series....
BEEN Waiting for quite some time for an upgrade.....

Must get one too. Although I would advise a doing also a normal leak on top, at least we can shorten the leak test time substantially.

lol. So true.

But, I would say that's part of the joy when going/doing custom loops.
Unless you get a leak that is..

No need.. the point of leak testing with air is that "air" molecules are smaller than water molecules and you're additionally testing the loop at much higher pressures than under water.. If it's gonna hold air at 0.5 to 0.75 bar for 15 to 30min, you can be absolutely sure it's gonna hold water.

Just thinking of my system and the millions of possible peak points I'll never see until it's to late.
Kind of why I went with a 400mm coolant reservoir as I'll definitely see a decrease of fluid as I've seen before with bad pump blocks from XSPC.
There's a reason their triple acrylic pump tops were discontinued......!! Three of them failed on me in the same way.
Now I use three bitspower POM Acytal pump tops with rotatable connectors between them and have never had issues ever since. Oh and can not forget the pressure relief valve I put in as well. Even though that was before the bitspower tops it didn't save the XSPC ones.
