Liquid cooling quick-disconnect Koolance QD3 male straight 13/10 mm no-spill, silver

The Koolance QD3 male straight 13/10 mm no-spill quick-disconnect is a metal connector designed for liquid cooling systems. It accepts 13/10 mm hoses and provides a straight, low-profile connection that enables fast, tool-free disconnection of coolant lines. The no-spill design reduces fluid loss during separation and is intended for repeatable connections in PC water cooling loops, radiators, pumps and other customized cooling assemblies.

Advantages

The metal construction offers mechanical durability and corrosion resistance suitable for long-term cooling setups. The no-spill coupling mechanism minimizes coolant leakage when disconnecting, reducing the need for additional draining or containment. Its straight male form factor keeps tubing runs compact and simplifies alignment during installation and removal. The quick-disconnect function enables fast maintenance and component swaps without tools.

Suitable for

• PC water cooling loops and custom desktop liquid cooling systems
• Radiator and pump connections where frequent disconnection is required
• Test benches and modular setups that need repeatable, low-leak couplings
• Small-scale custom cooling assemblies with 13/10 mm hose

Key specifications

• Connector type: straight male quick-disconnect
• Hose compatibility: 13/10 mm inner/outer hose sizing
• Material: metal body for increased durability
• Leak control: no-spill internal valve design to reduce fluid loss during disconnection
• Operation: tool-free connection and disconnection

How to use

Push the 13/10 mm hose securely onto the barbed portion of the male connector and secure with appropriate hose clamps or compatible fittings. Align the male QD3 with a matching female quick-disconnect coupler and push until the coupling engages. To disconnect, depress the release mechanism on the mating female coupler and pull apart; the no-spill valve closes to minimize coolant loss. Inspect seals and hose clamps periodically and ensure fittings are properly seated before pressurizing the loop.

Usage recommendations

Use the connector with compatible female quick-disconnects and hoses rated for PC liquid cooling. Before disconnecting, reduce loop pressure and, if practical, transfer or contain coolant to avoid spills. Regularly check metal surfaces and seals for signs of wear, and replace O-rings or clamps if leakage is observed.
