AL28xx-1 water-cooled

Make sure that the minimum diameter for water flow is at least 2.5 mm, and that the internal diameter of the hose is at least 4 mm.

1. Degrease the connector and the threaded holes. Allow the degreasing agent to evaporate completely before continuing.
2. Wrap Teflon tape around the thread of the connecting nipple.
3. Place the connection onto it and screw it tight. (This requires a torque of 4.0 Nm.)
4. The hoses must match the connectors.
   

Water cooling connections that can be used for hoses with an inside diameter of 4 mm are, for example, the Festo PU-4 pneumatic or the very flexible PVC hose Rauclair E 4x1. Both hoses and connections can withstand a pressure of 2 bar.
