Watercooling adapters

Im buying a thermaltake bigwater SE and a koolance RAM-30-V06 ram cooler. The problem I have is that the tubes for the water cooling are 1/4" and the tubes for the ram cooler are 1/2". How would i go about getting adapters for this?

I would need some Y splitters and something to for the change in tube size right? Does anyone know a good place to buy this?

Nevermind, i must have been tired last night when i read the diameters, because they are both 1/4" :/ sorry for triple posting
