UV Blue transparent tubing for custom loops

Alphacool AlphaTube HF 13/10 UV Blue Transparent is a 3 metre length of soft tubing with a 13 mm outer diameter and 10 mm inner diameter. The colour comes from the tube material itself, removing the need for dyed coolant and the particulate residue it can leave. Manufactured in Germany, the plastic blend is formulated for tight bending radii and easy handling during installation. The retail box contains a single 3 metre length identified by part number 18418.

Suits builders who want coloured loops without

This tubing suits anyone building a custom water-cooling loop who prefers vivid UV-reactive blue colour without the maintenance of coloured fluids. It works for both first-time builders and experienced users thanks to its flexible, kink-resistant character. It is not for systems that require hard tubing, larger bore sizes, or a different colour scheme. Buyers needing pre-bent shapes or reinforced wall construction should look elsewhere.

10 mm inner diameter matches 3/8 inch compression

The decisive specification is the 10 mm inner diameter, which corresponds to the 3/8 inch ID sizing used with standard compression fittings. If your loop uses fittings designed for a different bore, this tubing will not seal correctly. Verify the fitting specification before purchase.

Questions about this item

How often will the 13/10 mm tubing need replacement in a custom loop?

The tubing is manufactured in Germany for permanently high quality and contains no coloring particles, so it avoids the degradation caused by particle buildup that shortens the life of dyed coolant.

What is the first limit reached when bending the 13/10 mm tubing in tight routing?

The plastic mixture is developed for tight bending radiuses and easy handling in tricky situations, combining flexibility with kink resistance for both beginners and advanced users.

Does the UV Blue Transparent tubing affect coolant temperature or pump load during all-day operation?

The tubing adds no coloring particles to the loop, eliminating the strain those particles place on flow and heat transfer, so thermal performance and pump load stay consistent.
