1. EKWB EK-Cable PWM Fan Adapter for GPU
The EK Water Blocks EK-Cable PWM Fan Adapter allows you to connect your graphics card (provided it has the appropriate port) to PWM-controlled fans. This enables the cooling performance of the additional fans to be adjusted according to the PWM signal and the temperature of the graphics card, resulting in significantly more efficient cooling. The black cable features a 4-pin PWM fan socket and a 4-pin PWM fan connector. It is 50 cm long, allowing for a convenient connection to compatible components.
Note: The power limit of the fan connection on modern graphics cards is capped at two amps.
Technical details:
- Length: 500 mm
- Color: Black
- Connections:
- 1x 4-pin PWM fan connector
- 1x 4-pin PWM fan socket.

2. EKWB EK-Loop Leak Tester Flex
With the EK-Loop Leak Tester Flex from EK Water Blocks, accidents caused by a leaking water cooling system are a thing of the past. Traditionally, leaks were only discovered after some time and only after filling the system. With the EK-Loop Leak Tester Flex, you take a safe approach. This way, not only does your hardware stay dry, but so do your eyes. Technical details: Main color: Black, Accent colors: Gold, Gray, Silver.

3. EKWB Bitspower seal ring set for 1/4 inch thread
Water and electronics are known to not mix well. To ensure that the separation between these two areas remains 100% intact, especially in beloved water cooling systems, the sealing rings at the connections should be replaced regularly.
Similar to vehicle tires, these sealing rings have a long lifespan but lose elasticity over time and become brittle. Just as this can lead to reduced grip on the road and potentially cause accidents, it can also create problems in water cooling systems if a system becomes leaky.
In addition to the contact of water with electronics, the decreasing water pressure, increased noise due to air within the system, and potentially a total cooling failure pose significant risks to expensive hardware.
With this set of many O-shaped sealing rings, even extensive systems can be completely refurbished. The inner diameter is designed for G1/4 inch external threads. This is the most common thread standard, allowing for the sealing of nearly all screw threads with few exceptions. Be proactive!
Technical details:
- Material: Rubber
- For: G1/4 inch external threads
- Contents: approximately 50 pieces.

6. EKWB EK-Scalar Quad 2-Slot
The EK-Scalar Quad 2-Slot is designed to connect four graphics cards equipped with EK-Vector or EK-FC water coolers. The terminal connects directly to the respective VGA coolers, and additional fittings, seals, tubes, or hoses are required.
In this version, the terminal is made of transparent acrylic. The flow through this bridge is parallel. Therefore, two tubes run vertically through the connector, with water entering on one side, splitting, and flowing through the four VGA coolers, before being discharged on the other side. Advantage: All coolers receive evenly cold water. Disadvantage: However, this results in lower pressure.
Note: The terminal is only compatible with EK-Vector or EK-FC series water coolers.
Technical details:
- Material: Acrylic
- Color: Transparent
- VGA cooler connections: 4x
- Thread: G1/4 inch
- Delivery includes:
1x EK-Scalar Quad 2-Slot - Acrylic
2x G1/4-Plug
1x Mounting mechanism.

7. EKWB EK Loop Metal Tube Cutting Tool 3831109861783
The EK Loop Metal Pipe Cutting Tool is a small, handy tool specifically designed for cutting metal pipes. It is compatible with various metal pipes made of copper, brass, and nickel. The maximum size compatibility of the cutter is 32 mm outer diameter.
This allows you to shorten rigid metal pipes for your custom loop. It is made of stainless steel and can be adjusted to fit any pipe size commonly used in water-cooled PCs with hard tubing. It pairs perfectly with EK Loop metal pipes to cut them to the exact fit and superior aesthetics.
