I have a hard time finding silicone tubing, so here's an alternative I thought might work.
Here's the description from the webshop (translated from Norwegian):
"Made from EPDM-rubber. Doesn't dry or crack because of aging.
Can withstand temperatures between -50 and +120" (Celsius)
It's solid black in color and has 12,5mm inner diameter and 20mm outer diameter.
I'm worried that it might be too unflexible because of the thickness.

EPDM (a termolymer of ethylene, propylene and diene) is a product used quite extensively for roofing. In the roofing form it used in sheets about 0.045 inches in thickness. It is very flexible when used as a roofing sheet. I have never used EPDM as tubing however.

This tubing sounds like the material is 7.5mm in thickness or .3 of an inch in thickness. This is a ten fold increas in thicknes over the material I am familiar with.

When I say very flexible as a roofing sheet, I mean almost floppy and bends under its own weight. In a thicker tubing format I would imagine it is still flexible enough for a water cooling application.

I do know this material is very tough. You can stretch it, freeze it, thaw it, heat (within reason) and it maintains its integrity. It is used as a roofing membrane in very harsh climates (Canada)and as a roof it exposed to the sun and UV. Roofs made of EPDM can last in this environment for 20 years.

I would be sure that it would make it in a water cooling setup fine. The only drawback in my mind would be the black colour (personal taste).

Cool, I think I'll use that then.
It's cheaper than silicone too. The only place I found silicone tubing had it for $8 (85 NOK) per meter for 1/2" and $7 for 3/8"
This stuff costs $3 per meter.
12.5mm fits on 1/2" fittings, right?
