Product information

Description

The EK-Loop Leak Tester Flex from ek water blocks is a leak testing tool for computer liquid cooling systems designed to detect leaks in cooling loops and fittings quickly and safely. The unit includes a flexible hose, a revolvable male G1/4" (1/4") connection compatible with standard G1/4" cooling ports, a non-return valve to prevent air loss through the tester, a small hand pump for pressurizing the loop, and a top-mounted pressure gauge with a clearly marked safe testing zone. Use of the gauge and adherence to the marked safe pressure zone help limit the risk of over-pressurizing components during testing.

Advantages

The device reduces the time required to find small leaks compared with passive or slow methods, allowing testing to be completed within minutes. The flexible tube and revolvable G1/4" connector let you reach and connect to hard-to-access ports without stressing fittings or tubing. The integrated non-return valve and included pump enable controlled pressurization, while the dedicated gauge provides a visual reference for a predefined safe pressure range for EK products.

Suitable for (tasks / use cases)

  • Pre-commissioning leak checks of custom PC liquid cooling loops
  • Testing radiators, water blocks, reservoirs and tubing for leaks
  • Routine maintenance inspections after component changes or reassembly
  • Assembly verification when installing fittings and soft or hard tubing

Key specifications

  • Connection thread: male G1/4" (1/4") revolvable connector compatible with standard G1/4" ports
  • Flexible hose for reach and reduced mechanical stress on ports
  • Non-return valve to prevent backflow and air escape through the tester
  • Top-mounted pressure gauge with predefined safe testing zone (intended for EK components)
  • Includes a small hand pump for manual pressurization

How to use

Close the cooling loop and connect the revolvable male G1/4" connector of the tester to an available G1/4" port on the loop. Ensure all other ports and fill/drain openings are sealed. Attach the pump to the tester and operate it to slowly raise pressure while observing the pressure gauge. Keep the pressure within the predefined safe zone marked on the gauge; avoid exceeding the maximum indicated pressure to reduce the risk of damage. Inspect all fittings, tubing joints, radiators and components for pressure loss or visible signs of leakage during the test period. Release pressure through the tester according to the user manual after completing the check.

Usage recommendations

Read the supplied user manual before use and limit pressure to the gauge’s marked safe zone. The predefined safe maximum pressure on the gauge applies to EK components; exercise additional caution when testing non-EK parts. Perform testing in a dry environment over absorbent material to protect electronic components from potential leaks, and allow sufficient time for observation to detect slow or small leaks.
