[Solved] H220x fitting size question

[farhanorakzai]

I want to switch the fittings and tubing on an h220x. Can I put 2 if these in the radiator and cpu block?

Your cpu block and radiator both use G 1/4 threads which means you buy the fittings (with G1/4 threads) and then buy the tubing to match the fitting size, which in your case would be 3/8" ID x 1/2" OD.
