Four clear PETG tubes 13mm outer 10mm inner 80cm long

Alphacool

Alphacool Eisrohr 13/10mm PETG 80cm 4pcs Clear (18512)

SKU CH-FWWQ-SE3AS

Four clear PETG hard tubes, 13/10 mm and 80 cm each, bend at low temperatures for structured custom loops

  • Product typeTubing
  • Clear rigid tubing creates clean, structured loop aesthetics
  • 13 mm OD and 10 mm ID fit standard compression fittings
  • PETG material bends at lower heat than acrylic for easier shaping
  • Four 80 cm straight lengths provide ample tubing for most builds
  • Saw to exact length then seal with matched connectors for leak-free runs

Rigid PETG tubing for custom loops

Alphacool Eisrohr 13/10mm PETG tubing comes in four clear 80 cm lengths for building rigid custom water-cooling loops. The 13 mm outer and 10 mm inner diameter matches common hard-tube fittings. PETG material allows bending at lower temperatures than acrylic, so runs can be shaped to fit any chassis without extra angled adapters. Supplied as part number 18512.

Behaviour under sustained load

The rigid tubes maintain their formed shape permanently once bent and cooled, so coolant flow paths stay exactly as designed even during prolonged high-flow operation. PETG resists kinking better than softer tubing, preventing restriction that would otherwise increase pump workload over time. Clear walls allow visual confirmation that no particulate build-up occurs during extended use. No degradation of the bend radius occurs with continuous circulation.

Thermals noise and power draw

Tubing itself adds no active heat, noise or electrical draw to the loop; thermal performance depends entirely on the chosen radiators, blocks and pump. PETG transmits slightly more radiant heat from the fluid than insulated soft tubing, but the difference is negligible in typical configurations. Silent operation is inherited from the pump and fans, not the tubes. Power consumption remains zero.

Questions about this item

Does the 13/10mm PETG tubing generate any noise or heat when the loop runs continuously?

The tubing itself is passive; it adds no noise or heat because it contains no moving parts or electronics.

Which fittings or connectors do I need to already own to use these 13/10mm hard tubes?

You need compression fittings sized for 13 mm outer and 10 mm inner diameter to seal the tubes securely.

Can I mix these PETG tubes with older acrylic or glass hard tubes in the same loop?

Yes, as long as every tube shares the 13/10mm dimensions and matching fittings, they can be combined without leaks.
