just go to ur local hardware store.
ur looking at 2 sizes for barbs. Barb size and NPT threading size.
i am positive the magdrive pumps use 1/2" npt threading(i know it's way bigger than 1/2, more like a tad under an inch).
U say u use 1/2 id tubing as well as 3/8 id tubing.
If u flo in the following order:
==>Pump==>Rad==>Block==>
then u will need a 1/2" barbed 1/2"npt threaded barb fitting for the inlet of the pump. You will also need a 3/8" barbed 1/2" npt threaded barb for the output of the pump.
as far as increasing from 3/8" to 1/2" id tubing between ur rad and block? may i suggest a coupler from www.liquidcool.org . if u want a cheaper solution and have silicon tubing you could attempt to stretch the 3/8" id tubing coming from the rad over the 1/2 barb on the block.
Hope it helps
