Question Tubing size for watercooling?

[LaurX]

Hello everyone!

I would like to ask a question about tubing size for my watercooled PC.

I have G1/4 fittings (shown in picture) and I measured the inner diameter of it and it was 15 mm. I don't know what size tubes to pick! I tought all G1/4's are the same size without any difference in ID. So how I am supposed to insert a 12 mm OD tube inside this fitting?

You don't insert the hose into the fitting. One side is the g1/4 While the other side will correspond to your tubing size. And will be either a compression, barb or hard line tube compression.

Okay, so I already messed up... The fitting description says it's 14 mm and I already ordered 10/13 mm tubes...
