EKWB EK-Leak Tester

I got this after watching a random build guide on YouTube, didn't think it was going to be necessary but man was I wrong.I have worked on my build for about 2 weeks now, and finally got all the hard tubing cut, bent, and in place. I was so excited I almost forgot to leak test. I slapped on the leak tester on my fill port, and no matter how hard I pumped the needle wouldn't move at all. I was sure all my tubes were in place and properly sealed with fittings, so I started looking around for issues. I found my drain valve was set to open (that would've been a nightmare to fix). However that wasn't the issue.After being stumped, I just did the hard thing -- tear all the tubes off and start testing each individual component for issues. Didn't find anything. On a side note, I should have done that from the start, before putting any tubes on. So i start adding tubes one at a time, leak test for a few seconds, then add another. I got to my radiator tubes and wouldn't you know it, of the 4 tubes, 2 of them had major leak issues. I think it was a combination of not having them sized quite right and not entering the fitting at a perfect perpendicular angle (unfortunately I ran out of tubing so I was trying to make what I had cut work -- lesson learned!).Without this I would have leaked all over my case and components, as the radiator fittings are positioned at the top. I can't recommend this item enough.As a side note, someone else mentioned painting the needle white and I highly recommend to do so. The cover for the pressure gauge pulls right off (it's not glued or sealed or anything), just give it a little twist and pull. I used a silver sharpie, worked like a charm.

Used this when building my first water cooling loop and thankfully found out one of my connections wasn’t solid enough before I added any water. I then tightened the tubes and tested again to find no more leaks. Thank you EK for giving me the piece of mind I needed to fill up my PC for the first time. Will highly reccomend this to anyone building a water cooling loop for the first time or professionals testing their work on a routine basis. Super easy to use but I do want to mention that you must have a decent quality plug to test connections or your pressure will always drop (I tried using one that came with my radiator to no avail). You can buy them for like $7 for a 4 pack so it’s not a huge deal.

At first I thought the Tester leaked but it was the small flex hose connected to the pump that likes to untighten at the pump as you use it. Just keep it checked and works fine for me.

TLDR Version: Works great when you realize how to set it up. No instructions. Check the tester before use.Long version:I have been using the leak tester to verify the integrity of my water loops before filing. There are no instructions in the box, so you have to figure out how the it all works together. Once you look at it for a bit you can figure it out, but a minimal set of instructions would be nice. The well marked gauge provides clear indication of where the pressure for the system should be at. Things I would improve. 1) Directions included with the tester. 2) Some of these have been known to leak out of the box, Check you tester on a radiator or other simple in/out item before you check your whole loop to make sure the tester itself is not leaking. This can be fixed with a little plumbers tape on the gauge where it meets the body. 3) It would be nice if it had a marker needle. Meaning a needle that stayed at the pressure you put the tester to that didn't reset until you emptied the unit. That would make it easier to check for leaks. Overall, speeds up building water loops. Just a few design tweaks would make it perfect.

Essential for loop building. IGNORE THE GREEN AND RED ZONE ON THE GAUGE, it’s way too high for a loop! Even EK guides warn about putting too much pressure in a loop. 0,3 is all the pressure you need to test a loop.Also, use a couple of fittings and a length of soft tubing. Trying to attach this inside of the case is near impossible with that bulky gage. You need tubing to extend its reach. If your running hard tubing, you might have some challenges testing different points in the loop.Super solid construction, EK is top quality stuff.

Hi. This thing is an absolute must have item for anybody building a custom loop, it literally takes out all of the guess work and can save you days of work and frustration. I have leak tested everything in the build I'm working on and quickly found out that my stop fittings are faulty, so I could use some different ones and get right back to work without ever filling it. No leaks, no spills and no risks. I can't recommend this product enough.

Air leak testing is way easier and faster than testing with water, and air leak testers are also useful in helping drain your loop by pressurizing it while the drain port (the lowest port or line in your loop) is open.That being said, the gauge isn't the easiest to read in some scenarios and will move slightly if moved or bumped, but is accurate enough for the task.If I were to suggest any improvements, it would be to number the tick marks in the green test region, and color the needle to stand out better from the background.

The face of the gauge is off center, causing the paper face to contact the needle and keeping the needle from moving properly. That being said, its still usable, just the gauge is useless. I replaced the gauge and then pressure testing my system, found a leak before filling reservoirs, so worth the $$ and the wait it took for this to arrive.
