Quick Connect Shut-Off No Spill Couplings

Koolance quick disconnects (QDC) are specially designed no spill fittings which automatically shut-off coolant flow upon disconnection. The flow path is re-established when the couplings are connected. Quick disconnects are very useful for areas in a water cooling or plumbing system which are altered and moved frequently. They can also increase convenience when draining a  Liquid cooling system.

 Connected liquid cooling Quick Disconnects

All Koolance QD4 disconnects Compression fittings shutoffs work by having an internal valve mechanism which opens and closes as needed. Both male and female fittings contain a "plunger" that is spring-activated. When connected, the valves on both sides remain open to allow coolant to pass through. When disconnected, each side immediately self-seals. Koolance's current couplings are considered "no-spill" or "dry-break". This means very little coolant is freed upon disconnection. The insides of the quick disconnects fittings may be wet, but there is generally not enough liquid to form a drop on either side of the disengaged QDC Disconnects.
