Buis Alphacool 29127

The Alphacool 29127 tube is a flexible cooling tube engineered for liquid cooling loops in computer systems. With a 1.3 cm diameter and 30 cm length it is sized to support typical flow rates used in compact and mid-size systems. The tube is lightweight (approximately 43 g) and finished in blue, combining functional liquid transfer with a visible, coordinated appearance in custom cooling builds.

Advantages

This cooling tube offers consistent internal diameter and stable flexibility to maintain steady coolant flow while simplifying routing inside the case. Its lightweight construction reduces strain on fittings and mounts during installation. The blue exterior provides visual identification of the line and enhances the look of systems where component color matching is desired. Materials and dimensions are selected to be compatible with mainstream water-cooling fittings and components.

Suitable for

• Custom PC liquid cooling loops in compact and mid-tower cases
• Replacement tubing for maintenance or upgrades of existing cooling systems
• Prototype and test benches where short runs of coolant tubing are required

Key specifications

• Inner/nominal diameter: 1.3 cm
• Length: 30 cm
• Weight: 0.043 kg
• Color: blue
• Flexible tubing suitable for liquid coolant

How to use

Measure the required run length in your cooling loop and verify compatibility with your fittings and connectors before installation. Cut the tube cleanly with a sharp tubing cutter to avoid burrs, then push onto barbed or compression fittings until fully seated. Ensure clamps or compression rings are secured according to the fitting manufacturer’s instructions to prevent leaks. After assembly, perform a leak test with only the pump and reservoir powered, checking all connections for at least 15–30 minutes before powering other components.

Recommendations

Store the tube away from direct sunlight and extreme temperatures prior to installation. Regularly inspect visible tubing for signs of wear, discoloration or hardness, and replace if any degradation is observed. When using colored tubing in visible builds, consider matching with coolant and fittings to achieve the desired aesthetic while maintaining recommended maintenance intervals for the entire loop.
