Quick Disconnect Couplings

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.



 

QD1H Series

QD1H Series (3)

The QD1H series includes couplings for 3mm (1/8 inch) internal diameter hose and is physically the smallest size. No-spill quick disconnect couplings which push to connect with a negligible amount of coolant freed.

QD2 Series

QD2 Series (8)

The QD2 series includes couplings for 6mm (1/4 inch) internal diameter hose. No-spill quick disconnect couplings which push to connect with a negligible amount of coolant freed.

QD3 Series

QD3 Series (30)

The QD3 series includes couplings for 10 to 13mm (3/8 to 1/2 inch) ID hose, is the most popular size, and has the widest range of fittings. No-spill quick disconnect couplings which push to connect with a negligible amount of coolant freed.

QD4 Series

QD4 Series (8)

The QD4 series includes couplings for 13mm (1/2 inch) ID hose and is physically the largest size. No-spill quick disconnect couplings which push to connect with a negligible amount of coolant freed.
