Thread Size vs Fitting Size

[eTanium]

I need to look into getting fittings for a rig that I am building. I'm curious about the performance of flow when comparing the size of the threading on components (such as the radiator), to the size of the tubing.

Let me clarify. The thread size on most radiators seems to be 1/4. This leads me to believe that flow is really governed (pump speed aside) by the size of the threading of the fittings and not the size of the fittings themselves?

So, going with a larger diameter tube and/or fitting won't increase the flow of the loop, right? At that point, the size of the tubing/fittings is just about aesthetics, or am I not thinking about this correctly?

I am looking to do 1/2" tubing; I like the fact that it is big, and will be prominent in the PC case. So, I'll need 1/2 fittings, with 1/4 threads, right?

Thanks,

I don't think there is anything in it performance wise, not that I have heard of anyway.

For fittings you will want G1/4" thread, if you are going for compression fitting you have to match the size of the tubings OD and ID with the fittings OD and ID. So if you are using 1/2" ID 3/4" OD tubing you want 1/2" ID 3/4" OD compression fittings.

If you want barbs though you want the barbs to be wider than the tubing so it's a tight fit and the tubing grips on to the barbs, 7/16" OD tubing with 1/2" OD barbs are the best to go with.

Thanks.

Another question about kill coils... do they impede the flow in a loop? Could they have adverse reactions with any dye in the water?

A kill coil is a tiny piece of silver, you drop in your res, I won't hurt anything.

If your worried get a silver bullet.
