EK-Loop Leak Tester Flex

This product is intended for installation only by expert users. Please consult with a qualified technician for installation. Improper installation may result in damage to your equipment. EK Water Blocks assumes no liability whatsoever, expressed or implied, for the use of these products, nor their installation. The following instructions are subject to change without notice. Please visit our website at www.ekwb.com for updates.

Before you start using this product, please follow these basic guidelines:

• The Leak Tester's Tube Fitting requires only a small amount of force to screw it firmly in the G1/4 threaded port of the tested component, since the air seal is ensured by the rubber O-ring gasket.
• Use a Leak Tester only when all the components are tightly sealed together and before filling the loop with the coolant.

General Information

The EK-Loop Leak Tester Flex is a fast and safe way of testing for possible leaks in your liquid cooling loop. It features a revolvable male G1/4" connection port for direct attachment to standard ports in your liquid cooling loop. The other end has a non-return valve to prevent air escape. A mini pump for pressurizing the loop is included. Ensure pressure stays within the marked zone on the gauge to prevent damage to hardware.

The leak tester confirms that a newly made loop is watertight and ready for filling. It can also 're-certify' blocks that have been opened for cleaning and reassembled.

Components:

• Pressure Gauge: Displays the system pressure.
• Pressure Gauge Gasket: Seals the pressure gauge.
• Manifold: Central connecting piece.
• Mini Pump: For pressurizing the loop.
• Pump Connector with O-ring: Connects the pump and includes a seal.
• Filter Foam: Located within the pump connector.
• Plastic Check Valve: Prevents air backflow, inserted into the pump connector.
• G1/4 Tube Connector with O-ring: Connects to the component being tested.
• Flexible Tube: Connects the tester to the component.

How to Use the Leak Tester

Step 1: Connect to System

Ensure the system (Loop / Water Block / Distribution Plate / Reservoir / ...) is sealed everywhere except for one free G1/4 port. Screw the G1/4 Tube Connector of the leak tester into this port.

Step 2: Assemble Tester

Attach the Leak Tester's Flexible Tube to the G1/4 Tube Connector.

Step 3: Pressurize and Test

Use the Mini Pump to inflate the loop with air to the recommended pressure shown on the Pressure Gauge. Refer to the table below for specific charging pressures.

After pressurizing, wait a few moments for the pressure to stabilize. Note the pressure reading on the gauge. Wait for five (5) to fifteen (15) minutes and check for any drop in the needle. If the pressure remains stable, the loop is watertight. Remember that air leaks more easily than coolant.

Note: For systems with a smaller volume, pressure may fluctuate by +/- 0.02 bar due to temperature changes, which does not indicate a leak. ⚠️

What to Do in Case You Notice a Pressure Drop

Step 1: Check Fittings

If a pressure drop is detected, first verify that all fittings in the loop are securely attached. Check that components of the Leak Tester itself are not loose, including the Flexible Tube's fittings, Pressure Gauge, G1/4 Tube Connector (with O-ring), and Pump Connector.

Step 2: Check for Debris

In rare cases, debris can accumulate in the Plastic Check Valve, causing pressure loss. To check, unscrew the Pump Connector using a 4 mm Allen key. Remove the Check Valve and Filter Foam. Gently push them out of the Pump Connector with the Allen key.

If debris is found in the Check Valve, remove or blow it away. Reassemble the Leak Tester, ensuring the Filter Foam is correctly placed back into the Pump Connector.
