Description:

Soft and flexible, Norprene tubing is an excellent choice for low-maintenance cooling systems.  Being completely opaque, this tubing can help to reduce the chances of biological growth in your cooling system and is heat, ozone, and UV resistant.  To top it all off, according to the manufacturer's specifications, this size of Norprene tubing has a tighter minimum bend radius than any other 1/2" ID tubing that we carry! (granted, the Norprene is still quite a bit stiffer than R-3603)

A-60-G is the same grade of Norprene that is used by Swiftech in their H20-120 Compact Kit and Quiet Power P180 case.
