Hardtube fitting OPTIMUS for 12 mm rigid tubing, Satin Nickel finish

The OPTIMUS hardtube fitting for 12 mm rigid tubing with a satin nickel finish is a single mechanical connector designed for reliable joining of rigid coolant or fluid lines. Engineered for precise hardpipe installations, this fitting provides a compact, secure interface that helps route and seal 12 mm tubes in custom PC water-cooling loops and industrial tubing assemblies. The satin nickel surface offers a neutral metallic look while resisting everyday handling and installation wear.

Advantages

This single hardtube fitting delivers a mechanically secure connection without relying on adhesives or soft tubing compression. Its geometry is optimized for leak-resistant mating with 12 mm rigid tubes and for straightforward alignment in confined assemblies. The satin nickel finish reduces visible tooling marks and supports aesthetic integration with metal and neutral-toned systems. The component is suitable for both DIY and professional builds where precise tube routing and durable joins are required.

Suitable for

• Custom PC water-cooling loops using 12 mm rigid tubing
• Industrial or laboratory fluid lines with rigid 12 mm pipes
• Prototype and small-series assemblies requiring precise hardpipe joins
• Retrofit and maintenance work where a single, replaceable fitting is needed

Key specifications

• Compatible tube outer diameter: 12 mm rigid tubing
• Finish: satin nickel for a subdued metallic appearance
• Connection type: single mechanical hardtube fitting for rigid pipes
• Typical use: coolant and fluid lines in cooling loops and assemblies
• Material characteristics: machined metal surface suitable for mechanical sealing

How to use

Prepare the 12 mm rigid tube ends by cutting square and deburring to ensure flat contact surfaces. Slide the tube into the fitting until it seats fully and aligns with the fitting’s stop. Tighten according to manufacturer torque guidance or until a secure mechanical engagement is achieved; avoid excessive force that could deform the tube. Inspect the joint visually and, where applicable, perform a pressure or leak test appropriate for the system before putting the assembly into regular operation.

Recommendations

For best results, use with properly sized 12 mm hard tubing and verify that mating surfaces are clean and free from machining debris. During installation, support nearby tubing and components to prevent strain on the fitting. When used in coolant systems, follow fluid compatibility and system maintenance schedules to preserve sealing performance and finish appearance.
