Alphacool AlphaTube HF 10/13mm UV Black 3m PVC Tubing

Tubing for custom water loops

Alphacool AlphaTube HF provides a 3 m length of PVC tubing with a 10 mm inner diameter and 13 mm outer diameter. The UV Black finish reacts under ultraviolet light for visual effect. It is intended for builders assembling custom liquid cooling circuits who need a flexible conduit between blocks, radiators, pumps and reservoirs. The material operates reliably from -10 °C to 80 °C.

Flexible PVC with kink resistance

A hardness rating of 65-70 A-Shore gives the tube enough rigidity to resist collapsing on tight bends while remaining pliable for routing around components. The 13 mm outer diameter fits standard 13 mm compression fittings without adapters. Rated for a working pressure of 3 bar and a burst pressure of 18 bar, the tubing handles typical loop pressures with a wide safety margin. The 3 m roll allows multiple cut lengths for complex routing.

Replaces aged or mismatched tubing

This roll suits builders refreshing a loop where old tubing has clouded, stiffened or discoloured, or anyone moving from smaller-bore hose to a 10 mm ID for higher flow. The jump is worth it when the existing tubing shows surface degradation, when a colour change is desired, or when a longer continuous run is needed without splices. It does not suit builds requiring hard-line acrylic or PETG tubing, nor loops designed for smaller 8 mm ID fittings.
