Koolance QD3 quick-disconnect fitting female straight to 13/10 mm, no-spill, black

The Koolance QD3 quick-disconnect fitting female straight to 13/10 mm in black is a tool-free, no-spill coupling designed for liquid-cooling loops. This female straight quick-disconnect accepts 13/10 mm (outer/inner) soft tubing and provides a sealed connection that facilitates maintenance, component swaps and modular loop reconfiguration without requiring system drain or complex tools.

Advantages

This female QD features a no-spill mechanism that reduces coolant loss during disconnection and minimizes the risk of leaks. The straight inline design keeps tubing runs neat and reduces flow disruptions. Its push-to-connect operation enables fast, one-handed coupling and uncoupling, improving serviceability for PC water cooling systems and other liquid-cooling assemblies.

Suitable for

• PC water cooling maintenance and upgrades
• Modular or multi-loop cooling systems
• Quick component swaps (radiators, pumps, reservoirs)
• Test benches and development rigs where frequent disconnection is required

Key specifications

• Connection type: female quick-disconnect, straight inline
• Tubing compatibility: 13 mm outer / 10 mm inner soft tubing
• No-spill feature: built-in valve to reduce coolant leakage on disconnection
• Material and finish: black exterior finish designed for PC installations
• Operation: push-to-connect, tool-free coupling and uncoupling

How to use

Slide the compatible 13/10 mm soft tubing onto the hose barb until seated securely, then tighten any hose clamp if your loop design requires additional mechanical retention. To connect, align the mating male quick-disconnect and push the female fitting onto it until it locks; the built-in valve isolates flow during disconnection. When disconnecting, depress the release mechanism and pull the fittings apart; the no-spill valve will reduce coolant loss. Verify seals visually after connection and perform a leak check before returning the system to normal operation.

Usage recommendations

Use with tubing sized to 13/10 mm for best sealing performance and consider adding a hose clamp when operating at higher pump pressures. Inspect seals periodically and replace any fitting that shows wear or persistent leakage. When working on a live system, perform a controlled cooldown and catch any residual fluid to avoid damage to components.
