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.
All Koolance QD4 disconnects Compression fittings shutoffs work by having an internal valve 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 fittings may be wet, but there is generally not enough liquid to form a drop on either side of the dis engaged QDC Disconnects.
