Adapter 90° BitsPower for 12mm AD Hardtube to 12mm AD Hardtube, glossy black/blue

BitsPower 90° adapter for 12mm AD Hardtube to 12mm AD Hardtube in glossy black with blue accents is a right-angle fitting engineered for hard tubing liquid-cooling loops. It enables a compact directional change between two 12 mm hard tubes, allowing cleaner and more precise routing inside PC water-cooling systems. The adapter is made to match the outer diameter standard of 12 mm AD hard tubing and to maintain a sealed connection when used with compatible compression fittings.

Advantages

The adapter provides a tight 90° turn while minimizing the space required for tubing bends, which helps reduce stress on fittings and improves interior layout. Its glossy black finish with blue accents offers visual consistency with many custom loop builds. The component is intended for a long-lasting installation when paired with appropriate hard-tube fittings and properly seated seals, ensuring reliable coolant flow and reduced risk of leakage.

Suitable for

• Custom PC water-cooling loops using 12 mm AD hard tubing
• Compact or cramped case builds requiring right-angle routing
• Systems where aesthetic match with black/blue components is desired
• Upgrades or repairs where replacing large tubing bends is preferable

Key specifications

• Connection type: 90° right-angle adapter for hard tubing
• Compatible tube outer diameter: 12 mm AD hardtube
• Finish: glossy black with blue accents
• Material: metal alloy with machined surface finish (compatible with liquid cooling use)
• Application: internal PC liquid-cooling loops

How to use

Install the adapter by removing the compression rings from the mating fittings, insert the prepared 12 mm AD hardtube ends into the adapter until fully seated, then secure the compression fittings according to their manufacturer instructions to create a sealed joint. Ensure tube ends are cut squarely, deburred and cleaned before installation to prevent seal damage. After assembly, pressurize and inspect the loop for leaks before powering the system.

Recommendations

When routing hard tubing with this 90° adapter, measure and test-fit tube lengths before final tightening to avoid undue stress on fittings. Use compatible compression fittings rated for 12 mm AD hardtube and follow standard coolant and maintenance practices for PC water-cooling systems.
