Alphacool Eisrohr 12/9mm PETG HardTube 80cm Clear

This pack contains four clear PETG hard tubes designed for custom water cooling loops. Each tube measures 80 cm in length with a 12 mm outer diameter and 9 mm inner diameter. The 3 mm wall thickness provides strength while remaining workable for bending with moderate heat. They suit builders who want rigid tubing aesthetics.

Builders creating a custom open loop

The material is PETG, which requires significantly less heat to bend than acrylic alternatives and can be shaped without great effort. Cut edges must be chamfered using a fine file, sandpaper or a dedicated deburrer to prevent O-ring damage during assembly. This product is not for buyers who need flexible tubing or push-fit connections.

12 mm outer diameter with 9 mm inner diameter

The 12/9mm sizing determines compatibility with matching compression fittings and other loop components. Verify that every block, radiator, reservoir and fitting in your build uses this exact dimension before purchasing. The clear finish suits any coolant colour.

Questions about this item

How can I tell the 12/9 mm tubes are seated correctly after installation?

Press each tube fully into its fitting until it stops, then tug gently — the 3 mm wall should show no gap at the O-ring and the tube must not pull free.

What comes in the pack and what extra items are needed to finish a loop?

Four clear PETG tubes, each 80 cm long with 12 mm outer and 9 mm inner diameter; you must supply 12/9 mm compression fittings, a tube cutter or fine-tooth saw, chamfer tool or deburrer, and coolant.

Which version should I choose if my fittings are 12/9 mm?

This pack matches 12/9 mm fittings exactly — outer diameter 12 mm, inner diameter 9 mm, 80 cm length, four pieces — so select it when your loop uses that size.
