5. Aquatuning Spray bottle 500ml PE-LD

This spray bottle is filled with the coolant that you want to have in your system. By pumping, or compressing the bottle, the liquid is pushed through a tube directly into the expansion tank. Conversely, it is also possible to suck the liquid out by pumping on the bottle. This is particularly advantageous during modifications or when dismantling the water cooling system, as it prevents messy spills. The package also includes a cap to seal the spray bottle with the liquid. 

6. Alphacool Alpha Core ATX 24-pin jumper plug 1020417

The Alphacool Core ATX bridging plug is a simple but highly effective tool. Once the water cooling system is assembled, the system must be filled. To do this, the pump needs power from the power supply unit, and the system itself should remain unpowered for safety reasons. To be able to start the power supply without booting the entire computer, the 24-pin ATX connector is disconnected from the mainboard, thus deactivating the power supply. The 24-pin bridging plug is now plugged into the 24-pin connector of the power supply unit and the pump is connected to the power supply unit. After pressing the power switch, the power supply unit starts and the pump is supplied with power. This makes it very easy to fill the system.

7. Bitspower Touchaqua water outlet G1/4 inch male - pack of 2

The Bitspower Touchaqua water outlet is a practical accessory for water cooling circuits. The adapter consists of three parts: an adapter piece with an integrated outlet valve, a matching closure plug, and an adapter piece with G1/4 external and internal threads.

The adapter with the valve is installed in a free G1/4 port in the circuit and fitted with the closure plug. To drain the water, the closure plug must be removed and the other adapter piece screwed in. By screwing it in, the valve inside the adapter opens, allowing the water to escape from the system.
