ShutOff valves

[linger]

I want to know where i could get a valve that would go in between two tubes, and be able to close and open - shut off or on. I thought i could look in a plumbing store or something, but since its for a computer my dad says i should find something of higher quality that wont leak. Do you guys have any ideas, what to buy/ where to buy?
Thanks in advance

A plumbing store would have high quality stuff that won't leak...that is provided you take the proper precautions such as hoseclamps or sealant etc.... As far as I know, there aren't any "built for computer" watercooling valves, and even if there were, I would still trust sturdy metal plumbing fixtures anyway.

These are quick disconnects that shut-off.
