Purpose and user

The FormulaMod Airtight Tester GJQM-01 is a dedicated leak-pressure detector for custom water-cooling loops. It lets builders verify the integrity of blocks, radiators, tubing and fittings before any coolant is introduced.

Pre-installation checks

Confirm that every component in the loop presents a standard G1/4 thread or an adapter that matches the tester’s flexible connection. Ensure the system can be isolated from the rest of the hardware so pressure is applied only to the cooling circuit.

What the bundle changes

The package supplies the tester body and the quick-connect fittings needed for immediate use. No external pump or gauge is required, so the loop can be pressurised to 0.031 bar and inspected for leaks in a single step.

Questions about this item

What does the package contain and is anything extra needed?

The tester itself is supplied; you will need to provide your own tubing and fittings to connect it to the cooling loop.

How do I decide which version of the GJQM-01 to choose?

Only one model is offered, so there is no choice of versions or capacities to make.

What does the 0.031 bar figure mean when I use the tester on my loop?

It shows the pressure range the device applies, letting you confirm the loop holds that pressure without leaks.
