QD3 Female Quick Disconnect No-Spill Coupling, Female Threaded G 1/4 BSPP
Koolance patented quick disconnect no-spill coupling with automatic shutoff. Opposite is a female G 1/4 BSPP thread for attaching a fitting or barb. The disconnect side 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 approximately 0.2ml freed. Coolant volume lost upon disconnection will rise with internal pressure higher than 0.5kgf/cm2 (7psi).

Liquid Coolants
Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth.
