Koolance is a guarantee of excellent quality and aesthetics among connoisseurs, offering a wide range of products in the field of water cooling, from heat sinks to fittings, radiators, pumps, and hoses. The manufacturer knows exactly what it offers to its discerning customers.

The QD series of quick disconnects from Koolance allows for a very simple and practical way to interrupt the coolant circuit by simply pressing down on a metal ring. This is especially necessary in situations where hoses or water cooling components connected to them need to be frequently disconnected from the rest of the water cooling system. The higher the designation of the QD connection, the more robust and larger they are, making them suitable for larger hose diameters.

For example, consider an external radiator that you want to quickly and safely disconnect from your PC during transport to carry it separately. Or a water cooling component that you change frequently, whether out of experimental curiosity (CPU, chipset cooler) or due to regular upgrades (VGA cooler).

Two QD3 quick disconnects made of nickel-plated brass are connected or separated (one male, one female), with Koolance developing valves that, as the name No-Spill suggests, are designed to ensure a certain level of leak resistance. However, it should be noted that a hundred percent immediate sealing is not possible, and up to 0.2 ml of liquid may escape.

This quick disconnect in the new revision represents the straight male version with a G1/4 inch male outer thread.
