Radiator tube adapter Watercool MO-RA IV Heatkiller Tube Adapter – black

Watercool MO-RA IV Heatkiller Tube Adapter – black is a dedicated tube adapter designed to provide a secure connection between MO-RA IV radiators and soft or hard tubing in custom PC liquid-cooling loops. The adapter creates a stable interface that supports correct hose routing and helps reduce stress on fittings and radiator ports. It is intended for use with Watercool and Heatkiller components and is finished in black to match common chassis and cooling hardware aesthetics.

Advantages

The adapter offers a compact and robust solution for connecting tubing to MO-RA IV radiators, reducing the need for awkward or angled fittings. Its design promotes a tighter seal at the radiator interface, which helps minimize the risk of leaks when properly installed. The black finish provides a neutral appearance that integrates well with typical PC cooling setups. The adapter is lightweight and made to withstand the pressures and temperatures typical of custom water-cooling systems.

Suitable for

• Connecting soft tubing to MO-RA IV radiators
• Connecting hard tubing to MO-RA IV radiators with appropriate seals
• Custom PC liquid-cooling loops requiring secure radiator connections
• Radiator installations where compact, low-profile adapters are preferred

Key specifications

• Color: black
• Compatibility: MO-RA IV radiators and Watercool/Heatkiller water-cooling components
• Intended tube types: soft tubing and hard tubing (with correct seals)
• Function: provides a connection interface for tubing to radiator ports, facilitating hose routing and leak-resistant joins
• Form factor: compact adapter designed for radiator port alignment

How to use

Install the adapter by aligning it with the MO-RA IV radiator port and securing it according to the radiator and adapter mounting method. Insert the soft or hard tubing over the adapter connection point, ensuring the tubing sits fully on the sealing surface. Use appropriate clamps or compression fittings for soft tubing, or compatible seals and fittings for hard tubing, to achieve a reliable, leak-resistant connection. Verify tightness and alignment before filling the loop and perform a pressure or leak test at low power to confirm the integrity of the installation.

Usage recommendations

Use only compatible Watercool/Heatkiller-compatible fittings and appropriate tubing diameters. When installing hard tubing, ensure correct sealing components are used and avoid overtightening clamps or compression fittings. Always perform a controlled leak test after installation and before powering the system to reduce risk of coolant damage.
