Quick Disconnect Fitting Koolance QD3 male straight for 16/10mm tubing, no-spill, silver

The Koolance QD3 male straight quick-disconnect fitting is engineered for 16/10 mm (outer/inner) flexible tubing used in PC water-cooling and test-loop applications. Its no-spill mechanism enables disconnection without draining the entire circuit, while the straight-through design maintains unobstructed flow. Constructed from metal with a silver finish, this fitting provides a secure, corrosion-resistant connection suitable for repeated coupling and decoupling during maintenance or component swaps.

Advantages

The no-spill design reduces the risk of leaks and fluid loss when disconnecting, simplifying maintenance and component replacement. Metal construction increases mechanical durability compared with plastic alternatives and the straight profile minimizes flow resistance in compact routing layouts. The fitting is compatible with common soft tubing sizes of 16/10 mm, allowing reliable sealing and firm hose retention.

Suitable for

• PC liquid-cooling loops requiring occasional component removal or upgrade
• Test rigs and benches where frequent hose changes are needed
• Maintenance tasks that demand quick, no-drain disconnection
• Custom cooling builds with 16/10 mm flexible tubing

Key specifications

• Intended tubing size: 16 mm outer diameter, 10 mm inner diameter
• Connection type: male straight quick-disconnect
• No-spill coupling mechanism for reduced fluid loss on disconnect
• Material: metal construction with silver finish
• Flow characteristic: straight-through profile for minimal obstruction

How to use

Prepare tubing by cutting squarely and sliding it onto the barbed or push-fit portion of a compatible hose end, ensuring the inner diameter of the tubing matches 10 mm for a secure fit. Insert the mating female quick-disconnect until the coupling locks; verify the connection by gently pulling the hose to confirm retention. To disconnect, depress the release mechanism on the mating half and separate the fittings; the no-spill valve reduces fluid escape but some residual liquid may remain in the line, so use absorbent material or a small catch container as needed.

Usage recommendations

Use with coolant types compatible with metal fittings and common PC loop additives. Inspect sealing surfaces periodically and replace O-rings if wear is detected. When planning tubing runs, allow clearance for coupling and uncoupling operations and avoid excessive bending at the fitting entry to maintain a reliable seal.
