AlphaTube HF clear PVC tubing 8 mm ID 11 mm OD

This Alphacool AlphaTube HF is a clear PVC tube made for custom water-cooling loops. Its 8 mm inner diameter and 11 mm outer diameter suit standard push-fit or compression fittings. The three metre length gives enough run for most single-loop builds. It arrives new and ready to cut to length.

Working limits of the PVC material

The tube is rated for a working pressure of 2 bar and a burst pressure of 8 bar. Its hardness falls between 65 and 70 A-Shore, balancing flexibility with kink resistance. Operating temperature spans -10 °C to 80 °C, covering typical coolant ranges. Exceeding these pressures or temperatures can cause deformation or rupture.

Installation notes and common pitfalls

The tubing cuts cleanly with a sharp blade and slides over barbed or compression fittings without excessive force. Warm water can soften it for tight bends, but overheating risks permanent distortion. The main errors are cutting lengths too short, leaving no slack for component movement, and skipping fitting inserts that prevent collar crush.

FeaturesThe AlphaTube HF tubing has the perfect flexibility to be easily installed. It is flexible enough to be laid without effort, but at the same time rigid enough that it will not kink easily, even with tighter bending radii.

Questions sur cet article

Should I choose the 8 mm inner diameter or the 11 mm outer diameter for my fittings?

Both figures describe the same tube: 8 mm is the bore that carries coolant, 11 mm is the outside wall that the compression fitting seals against. You need fittings rated for 8 mm ID / 11 mm OD.

What does the 2 bar working pressure mean once the loop is running?

It limits the continuous pressure the pump can generate to roughly 2 bar; above that the tubing may deform or leak, so set pump speed and reservoir height to stay below this value.

How does the 65-70 A-Shore hardness affect bending in a real build?

The mid-range PVC hardness keeps the tube pliable enough for tight bends without heat, yet stiff enough to resist kinking when routed around GPU blocks and radiator ports.
