Koolance QD3 female straight quick-disconnect fitting 16/10 mm no-spill, silver

The Koolance QD3 female straight quick-disconnect fitting 16/10 mm no-spill, silver is a precision component for PC liquid cooling systems and custom water-cooling loops. Designed for 16/10 mm (outer/inner) flexible tubing, this no-spill female quick-disconnect enables fast, tool-free disconnection and reconnection of loop sections while minimizing coolant loss. Constructed with a silver finish, the fitting provides a straight inline connection that preserves flow path alignment and supports routine maintenance, upgrades, or component replacement without draining the entire loop.

Advantages

The no-spill mechanism reduces the risk of coolant leakage during disconnection, maintaining system cleanliness and protecting electronic components. The straight female quick-disconnect design simplifies plumbing by keeping tubing runs linear and minimizing bends. Installation and removal are tool-free and quick, which speeds up maintenance and component swaps. Durable materials and a precise sealing interface ensure a reliable connection under normal operating pressures of PC cooling loops.

Suitable for

• Custom PC liquid cooling loops using 16/10 mm flexible tubing
• Maintenance and rapid component replacement without draining the entire loop
• Inline break points for radiator, pump, reservoir, or GPU/CPU blocks
• Systems where minimizing coolant spillage during disconnection is important

Key specifications

• Connection type: female quick-disconnect, straight inline
• Compatible tubing size: 16 mm outer diameter / 10 mm inner diameter
• Leak prevention: no-spill design with integrated valve mechanism
• Finish: silver
• Operation: tool-free connection and disconnection
• Typical application: PC liquid cooling and custom water loops

How to use

Ensure tubing is cut cleanly and pushed fully onto the barb or hose adapter specified for 16/10 mm tubing. Insert the mating male quick-disconnect into the female fitting until the locking mechanism engages and verify a secure seal. To disconnect, follow the fitting’s release procedure to actuate the no-spill valves and separate the halves; perform disconnection over an absorbent surface or container as an extra precaution. After reconnection, check the joint for leaks and run a brief leak test under normal operating conditions before returning the system to full duty.

Usage recommendations

Use compatible 16/10 mm tubing and verify that the male coupling matches the QD3 series to ensure proper valve operation. Periodically inspect seals and perform leak tests after installation or maintenance. Avoid excessive twisting or bending at the connection point to maintain seal integrity and optimal flow.
