HardTube 16/12mm 90° Plexi

The Alphacool HardTube is a rigid PMMA tube designed for custom water-cooling loops. It replaces flexible PVC hose with a structured, tidy appearance. Builders who want a clean, professional aesthetic will appreciate the defined lines. It is not suited for loops that require tight, tool-free bends or frequent reconfiguration.

20cm and 40cm straight lengths

Each package supplies pre-cut tubes in 20cm and 40cm segments with a 90° angled profile. The 16mm outer and 12mm inner diameters fit standard HT compression fittings. Longer runs or complex routing will need additional straight tubes or a bending tool. Builders needing continuous lengths beyond 40cm must source extra pieces separately.

Sealed HT connector system

The plexi tubes join with Alphacool HT connectors that create a completely sealed joint without extra sealing steps. This simplifies assembly and reduces potential leak points. The rigid material demands accurate measuring and cutting before final installation. Loops that must navigate around tall components without angled fittings will find the fixed 90° shape limiting.

Questions about this item

Will the 16/12mm tubes fit alongside my existing 12mm fittings?

The tubes have a 16mm outer and 12mm inner diameter, matching standard 12mm compression fittings.

How can I confirm the 90° bend seals properly after installation?

Pressurise the loop and inspect each joint; the HT connectors create a completely sealed connection when fully seated.

Are the Alphacool HT connectors included or must I buy them separately?

The box contains the 20cm and 40cm plexi tubes only; HT connectors are sold separately.
