The wishlist name can't be left blank

PC water cooling check valves are simply one-way valves, allowing the flow of water freely in one direction and not at all in the other. Check valve fittings can be useful when filling a new system, as they prevent the coolant from flowing backward in the loop when power is shut off to the coolant pump. They will prevent backflow in any situation. Check valve fittings are available from TITAN RIG in multiple colors to match your custom PC.
