hey guys, I'm starting my first watercooling project and looking for suggestions for tube ID/OD sizing. For the ID, anything that is widely available for both fitting and tubing. OD for Tubing I'd like something in the middle; not too thin and not too thick.
1/2" inside is pretty standard. if you want a tight fit then you can get 7/16 and then theyll be really hard to get on the barbs but you can heat them or just give them a good push. thats good if youre using barbs and dont want clamps. if you are using clamps or compresion fittings then 1/2" is good.
for OD, you either have 5/8" or 3/4". 3/4 is less likely to collapse when you bend it, but its a lot bigger and doesnt look as good. 5/8" can collapse if you make too tight of a turn. personally i think 1/2" ID 5/8" OD is the best size, but the brand (material) is also important, maybe some people can give you suggestions on that, i dont know anything.
