Clear hardline tubing kit

This pack contains four 80-centimetre plexi tubes with 16-millimetre outer and 13-millimetre inner diameter. They replace flexible PVC hose in custom water-cooling loops for a rigid, structured appearance.

Bending and sealing notes

Tubes are shaped with a dedicated bending tool so no angled fittings are required. Connections must be pushed straight into Alphacool HT fittings with firm pressure; the supplier warns that Monsoon fittings are not compatible.

For custom-loop builders wanting rigid runs

Suits enthusiasts building a hardline loop who can bend acrylic tube and own matching HT connectors. Not for installers who prefer flexible tubing, lack a bending tool, or plan to use Monsoon or other non-HT fittings.

Questions about this item

How do I confirm the 16/13mm tubes are seated correctly after installation?

Push each tube straight into the HT connector until it bottoms out; a firm, even fit with no visible gap means the seal is complete.

What comes in the 4-pack and which fittings must I purchase separately?

The box contains four 80 cm clear plexi tubes (16 mm OD, 13 mm ID); you need Alphacool HT connectors — Monsoon fittings are not compatible.

Should I choose the 16/13mm 80 cm pack or the 13/10mm version for my loop?

Pick 16/13mm when your blocks and radiators use 16 mm fittings; choose 13/10mm only if every component in the loop is sized for 13 mm OD tubing.
