Tubing Alphacool 18633 trasparente PETG 14mm

The Alphacool 18633 transparent PETG tubing is designed for computer water-cooling loops and offers a clear, durable hard tube solution. With an outer diameter of 14 mm and a wall thickness of 3 mm, these PETG tubes combine strength with relatively easy bending and installation. Each pack contains four 80 mm segments, each weighing approximately 58 g and finished to provide a clean visual appearance in custom cooling builds.

Advantages

These PETG hard tubes are highly transparent and require less heat to bend than PMMA (acrylic) alternatives, making shaping and fitting simpler for custom loops. The 3 mm wall thickness provides good mechanical strength while still allowing controlled bending without excessive effort. The tubes are easy to cut and finish for neat terminations with standard fittings used in computer cooling systems.

Suitable for

• Custom PC water-cooling loops
• Visible tubing routes in gaming or workstation builds
• Replacement or upgrade of existing PETG hard tubing

How to use

Measure and mark the required tube lengths for your loop, then cut the PETG tubes using an appropriate tube cutter or fine-toothed saw. After cutting, chamfer and deburr the inner and outer edges with a fine file, sandpaper or a dedicated deburring tool to ensure smooth mating surfaces and to prevent damage to O-rings in fittings. Heat the tube gently and evenly when bending, using a heat gun at moderate temperature; PETG requires less heat than acrylic, so avoid excessive temperatures. Fit the finished tubes into compatible compression or barbed fittings, making sure O-rings seat correctly for a leak-free connection.

Recommendations

Do not apply excessive heat when bending PETG; use controlled, even heating and support the tube while shaping. Always chamfer and deburr cut edges to protect fitting O-rings and ensure reliable seals.
