Koolance is among connoisseurs a guarantee of excellent quality and appearance and provides a wide range of articles in the field of water cooling, ranging from radiators and heat sinks on fittings to pumps and hoses. The manufacturer knows exactly what it offers its discerning customers.
The QD-series of fasteners of Koolance enable a very simple and practical manner with a simple pressing down of a metal ring to interrupt the coolant circulation. This is necessary especially in situations where it must frequently hoses or integrated water cooling components are decoupled from the rest of the water cooling system. The higher the name of the QD connectors, the more massive and larger these run and are accordingly for larger tube diameters.
Koolance patented quick disconnect no-spill coupling with automatic shutoff. 13mm (1/2in) ID, 19mm (3/4in) OD female straight connection with compression fitting. It will only fit a Koolance QD3 male quick disconnect.
After pulling the ring on the female QDC side, the quick-disconnect fittings will separate. Liquid on both sides will be automatically obstructed with only 0.5-1mL freed with approximately 0.2ml freed. Coolant volume lost upon disconnection will rise with internal pressure higher than 0.5kgf/cm2 (7psi).
