EK-Loop Leak Tester Flex 3831109848388 The EK-Loop Leak Tester Flex 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-Loop Leak Tester Flex does the job within minutes. This product has a flexible tube on one end, allowing you to easily reach any port in your loop and avoid stressing it when pumping. It is fitted with a revolvable male G1/4” connection port so it can be directly screwed into any standard G1/4” port in your liquid cooling loop. The other end is hooked up with a non-return valve which will make sure that no air is escaping through the tester unit itself. A small pump for pressurizing the loop is also included. The top-mounted pressure gauge is custom made for liquid cooling loop testing purposes which clearly marks the safe pressure for testing. 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-Loop Leak Tester Flex.
