6.4.7 Cooling Circuit Pipes
The pipes used in the cooling circuit are PA11 plastic pipes with a diameter of Ø16/13 mm (0.63/0.51 in) (Rilsan model code
BESNOP40TL).
There are 2 ways to make permanent bends to the pipes.
l The quickest and easiest way is to make the bend in the air by bending it by hand. Do this if only 1 bend is needed and the
dimensions do not matter, or the dimension can be adjusted by cutting the pipe after bending.
l If multiple precise pipes with several bends are needed, it is recommended to use a bending jig. There are commercial jigs on the
market (for example, Eiskoffer Bending Kit from Alphacool), but the jig can be also self-made from plywood or some other easy-to-
work material. But the material must be able to withstand at least 200 °C (392 °F).
Required tools for bending the pipes:
l Gloves
l Adjustable heat gun
l Round silicone rubber cord
¢ Ø12–12.5 mm (0.47–0.49 in)
¢ Solid
¢ Hardness: minimum 60 Shore A, recommended >70 Shore A
Recommended tools for bending the pipes:
l Water bucket or sink
l Distilled water
l Bending jig
