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. Flexible Hose & Rotary Male G1/4 Connection 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 rotary 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. Quality Pressure Gauge With Color Coded Safe Testing Area 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. Review: とても使いやすい - θ²·γ£γ¦γ‚ˆγ‹γ£γŸγ§γ™ Review: Works - Works as intended, took 2-3 weeks to deliver, but works and is good metal material. The pump stick can get unscrewed constantly by small movements, so you have to tighten that before pumping constantly, small annoyance. Connects into an EK GPU water block and Corsair hydro X attachments. ## Features - The EK-Loop Leak Tester Flex is a fast and safe way of testing for possible leaks in your liquid cooling loop. - Flexible tube on one end, allowing you to easily reach any port in your loop and avoid stressing it when pumping - 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 - Hooked up with a non-return valve which will make sure that no air is escaping through the tester unit itself - Top-mounted pressure gauge is custom made for liquid cooling loop testing purposes which clearly marks the safe pressure for testing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09XZ9PBNX | | Best Sellers Rank | #15,229 in Automotive ( See Top 100 in Automotive ) #6 in Automotive Cooling & Water Pump Tools | | Brand | EK | | Brand Name | EK | | Color | Black | | Colour | Black | | Compatible Devices | Liquid cooling systems with standard G1/4" ports | | Customer Reviews | 4.3 out of 5 stars 147 Reviews | | Global Trade Identification Number | 03831109848388 | | Included Components | 1 product | | Item Dimensions | 10 x 5 x 1.3 centimeters | | Item Weight | 0.29 Kilograms | | Item dimensions L x W x H | 10 x 5 x 1.3 centimeters | | Item weight | 0.29 Kilograms | | Manufacturer | EK Water Blocks | | Measurement Type | Leak Tester | | Model | 3831109848388 | | Part Number | 3831109848388 | | Power Source | Corded Electric | | Power source | Corded Electric | | Specification Met | Electrical Safety Standards | | Style | Custom | | Style Name | Custom | | Unit Count | 1 Count | ## Product Details - **Brand:** EK - **Power source:** Corded Electric - **Style:** Custom - **Colour:** Black - **Item weight:** 0.29 Kilograms ## Images ![EK Water Blocks EK-Loop Leak Tester Flex - Image 1](https://m.media-amazon.com/images/I/511HSodCnPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ とても使いやすい *by M***M on 29 September 2023* θ²·γ£γ¦γ‚ˆγ‹γ£γŸγ§γ™ ### ⭐⭐⭐⭐⭐ Works *by S***N on 23 January 2024* Works as intended, took 2-3 weeks to deliver, but works and is good metal material.
