Hardtube fitting OPTIMUS 12 mm, strieborná – samostatný upínací konektor pre pevné chladiace rúrky

OPTIMUS hardtube fitting for 12 mm rigid cooling tubes in a silver finish is a single compression-style connector designed to join or route hard tubing in liquid cooling loops. It is compatible with rigid tubes that have a 12 mm outer diameter and provides a compact, metal-bodied connection point for directing coolant between components. The fitting is intended for use in PC water cooling systems, custom loops, and radiator or component terminations where a secure, neat, and low-profile junction is required.

Advantages

The single compression design simplifies installation of 12 mm hard tubes by providing a straightforward clamping mechanism that secures the tube without requiring additional adapters. Its metal construction and silver finish offer mechanical stability and a neutral aesthetic that integrates with a wide range of system builds. The fitting is engineered to provide a leak-resistant joint when installed correctly, helping maintain loop integrity and consistent coolant flow.

Suitable for

• Joining two 12 mm outer-diameter rigid cooling tubes in a liquid cooling loop
• Routing hard tubing between radiator, pump, reservoir, and water blocks
• Making compact turns or transitions in custom PC water cooling builds
• Replacing or upgrading existing rigid-tube connectors in a system

Key specifications

• Compatibility: rigid cooling tubes with 12 mm outer diameter
• Connection type: single compression-style connector for hard tubing
• Material: metal body with silver finish (visual and mechanical durability)
• Seal method: compression clamping for leak-resistant joint when installed correctly
• Typical use environment: PC liquid cooling systems and custom loops

How to use

Prepare tube ends by cutting them square and deburring to ensure a smooth mating surface. Slide the compression collar or nut over the tube, insert the tube fully into the fitting until it seats, then tighten the compression collar to the manufacturer-recommended torque so the tube is clamped without deforming. Verify alignment of connected components before final tightening. After assembly, pressure-test the loop or run the system while monitoring for leaks and recheck connections after an initial run-in period.

Recommendations

Use only rigid tubing with the specified 12 mm outer diameter and ensure tube ends are clean and free of chips. Tighten the compression collar evenly and avoid over-tightening to prevent tube damage. Perform leak testing after installation and periodically during maintenance. Combine with compatible fittings, gaskets, and mounting practices recommended for PC liquid cooling systems.
