## Overview

The EKWB EK-Leak Tester is an essential tool for any liquid cooling enthusiast, designed to quickly and safely test for leaks in your cooling loop. Made from high-quality CNC machined aluminum, it features a custom gauge for precise pressure readings and comes with a pump for easy pressurization. Its universal G1/4" fitting ensures compatibility with a wide range of systems.

## Description

The EK-Leak Tester is 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 become messy. The EK-Leak Tester does the job almost instantly!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 into 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 which will make sure that no air is escaping through the tester unit itself. The small pump for pressurizing the loop is also included.In order to prevent damage to your liquid cooling loop, keep the pressure only in the predefined zone marked on the gauge. Please read the user manual before using the EK-Leak Tester!Keep in mind that the pre-defined safe maximum pressure defined on the gauge is for EKWB products only. EKWB cannot guarantee for non-EK products failing under the predefined safe zone marked on the gauge.Enclosed:- EK-Leak tester- Small pump Model: 3831109816738

Review: AMAZING PRODUCT!!! Perfect for noobs or pros - 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.
Review: Must have for any new water cooling build - 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.

## Questions & Answers

**Q: How would the gauge assembly hold up to contact with liquids (left in loop permanently)?**
A: Lol this gauge is to test the loop before you add any liquid if your loop hold air for 30 minutes then you good to go

**Q: Is it normal to see a small amount of pressure drop if I leave for a few hours or overnight?**
A: You shouldn’t have no pressure loss. You shouldn’t leak test for a few hours or overnight. 30 minute leak test with zero pressure loss your 100% to go to fill with liquid.

**Q: How are the 0.05 bar increments measured on the guage? Is it every 2 lines or 1 line?**
A: every line is around 0.05 bar,
I say around since you have nine lines between 0 to 0.25 and 10 lines between 0.25 to 0.5

**Q: Will this work when putting all tubes together then doing the leak test on the fill port? I read someone was doing it individually how??**
A: The way you are thinking is by building your whole loop, while that will work, if you do end up having a leak it'll be a pain to find it. Testing individually would by pumping up each block/pump/reservoir/radiator individually as to isolate and possible leaks immediately. If you use the one by one method I'd conduct another test once its all built.

### ⭐⭐⭐⭐⭐ No leaks, no spills, no risks.
*by T***S on April 24, 2021*

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.
