Alphacool AlphaTube HF 11/8mm UV Black 3m

This PVC tubing is made for custom water-cooling loops and comes in a UV-reactive black finish. It ships as a single 3 metre length with an 11 mm outer diameter and 8 mm inner diameter, matching 11/8 mm compression fittings. The material carries a 65-70 Shore A hardness rating for a balance of pliability and shape retention. Builders who want a coloured, UV-active run will find it suited to their aesthetic goals.

Flexibility and kink resistance limits

The hose is flexible enough to route without force, yet rigid enough to resist kinking at tighter bending radii. Its working pressure is rated at 2 bar with a burst pressure of 8 bar, and it operates between -10 °C and 80 °C. Loops that run higher pressures or temperatures exceed the rated envelope. Installers who need extreme tight bends without any deformation should verify the minimum radius against their layout.

Capacity and headroom for typical loops

A single 3 metre pack covers most single-loop builds with CPU and GPU blocks, leaving a small margin for routing errors. Larger configurations with multiple radiators, distribution plates or parallel runs will likely require a second pack. The 8 mm inner diameter supports standard flow rates for common D5 or DDC pumps. Systems demanding higher flow through restrictive blocks may need larger-bore tubing instead.

Questions sur cet article

Should I pick the 11/8mm size or a different diameter?

Choose 11/8mm when your fittings are made for 11mm outer and 8mm inner diameter; other sizes will not seal on these barbs.

What does the 65-70 Shore A hardness mean once the tube is in my loop?

It gives a firm yet pliable feel that resists kinking on tight bends while still pushing onto barbs without excessive force.

The spec lists 8 bar burst and 2 bar working pressure — what does that cap in practice?

Normal loop pressure stays well below 2 bar, so the 8 bar burst rating provides a wide safety margin against accidental over-pressure.
