Quick Disconnect Couplings
Koolance quick disconnects couplings are specially designed fittings which automatically shut-off coolant flow upon disconnection. The flow path is reestablished when the QDC couplings are reconnected. Quick disconnects are very useful for areas in a cooling or plumbing system that are altered and moved frequently. They can also increase convenience when transporting or draining a system.
