Hardtube-aansluitset OPTIMUS voor 12-mm-buizen, 6-pack met installatiegereedschap, zwart

OPTIMUS hardtube fitting set for 12 mm tubing contains six precision fittings and a dedicated installation tool in a black finish. The set is engineered for secure, leak-resistant connections with 12 mm rigid (hard) tubing in liquid-cooling loops and custom cooling systems. Components are sized to match 12 mm outer-diameter hard tubes and are intended to simplify assembly, maintenance and upgrades for PC water-cooling systems and similar applications.

Advantages

The fittings provide a stable mechanical connection for rigid tubing, reducing the risk of movement-related leaks and maintaining consistent flow paths. The included installation tool streamlines the fitting process, ensuring proper seating and alignment of the tube into each connector. The black finish offers a neutral aesthetic that integrates with a range of system styles while providing durable surface protection.

Suitable for

• Assembling or upgrading PC liquid-cooling loops using 12 mm hard tubing
• Custom liquid-cooling projects requiring several fittings for multiple runs
• Maintenance tasks where reliable tube reconnection and leak prevention are needed
• Systems where a black visual finish is preferred for component uniformity

Key specifications

• Fits rigid tubing with 12 mm outer diameter
• Set contains six fittings and one installation tool
• Material: metal construction with protective black finish (visual and corrosion resistance)
• Connection type: compression-style hardtube fittings designed for secure mechanical grip
• Suitable for liquid-cooling applications at typical PC operating pressures and temperatures

How to use

Prepare the 12 mm hard tubing by cutting square and deburring the end to ensure a clean, flat surface. Slide the fitting components onto the tube as required by the fitting design, then insert the tube into the receiving port until fully seated. Use the supplied installation tool to apply even pressure and confirm correct engagement between tube and fitting. After installation, visually inspect each connection and perform a pressure or leak test according to your system maintenance routine before powering the system.

Recommendations

Use appropriate cutting and deburring tools for 12 mm hard tubing to avoid damaging the tube bore or outer surface. Always perform a controlled leak test after assembly and follow coolant manufacturer's guidelines for compatibility with metal fittings and finishes.
