It's the case as shown above with build in radiator +dual pump (1000L/h) & reservoir.
All the tubes have the 1/4" size :-/
Well...not really. The problem is that the pneumatic fittings used by A-C are designed for a specific outside diameter (OD) hose. Their hose is 6mm ID and 8mm OD. The Koolance hose is 6mm ID and 9mm OD. But there is a solution! I believe you can use A-C hose on your Koolance coolers and radiator parts as the Koolance devices use ferrel-less compression fittings that need 6mm ID hose and I don't think the extra 1mm on the OD will affect the nut from going over the tubing.

Another possible solution is to change over the G 1/8 fittings on your A-C cooler to the one you need. You can see this discussion also at the [H]ardForum link listed above. ;D
