Cooling system accessory BitsPower BP-MBDG14AALPI — brass, black finish

BitsPower BP-MBDG14AALPI — brass, black finish is a metal cooling system accessory intended for use in PC liquid- and air-cooling assemblies. Machined from brass and finished with a matte black e-plating, the component is designed to provide a high-flow passage and long-term resistance to corrosion. The part integrates an O-ring concealment feature and an adjustable pipe length range to support direct-connection setups and multi-GPU cross-connection layouts.

Advantages

The brass construction combines mechanical strength with good thermal stability and corrosion resistance, while the matte black e-plated surface improves wear resistance and provides a uniform appearance. The true hi-flow internal geometry reduces hydraulic restriction for improved coolant circulation. The concealed O-ring design protects the sealing element from exposure and simplifies aesthetic integration in visible builds. The adjustable pipe length enables flexibility during installation and alignment.

Suitable for

• Custom water-cooling loops in desktop PCs
• Cross-connection between graphics cards (multi-GPU) or direct connections between cooling blocks
• Upgrades or repairs where a durable metal connector is preferred
• Builds requiring a matte black aesthetic and corrosion-resistant fittings

Key specifications

• Material: brass with matte black electroplated finish
• Flow design: high-flow internal geometry
• Sealing: concealed O-ring sealing interface
• Adjustability: adjustable pipe length range 22–31 mm
• Compatibility: for direct-connection and multi-GPU cross-connection applications
• Standards: RoHS compliant

How to use

Install the accessory as part of the coolant path according to your loop layout, ensuring mating surfaces are clean and free of debris. Select the required pipe insertion depth within the 22–31 mm adjustable range to achieve proper alignment with adjacent blocks or fittings. Seat the O-ring and engage the connector until the concealed seal is fully compressed; verify that threads or locking features are correctly engaged if present. After installation, perform a pressure or leak test with coolant to confirm a watertight connection before powering the system.

Recommendations

Use compatible soft or hard tubing and fittings designed for PC water-cooling systems; avoid overtightening metal parts to protect threads and the concealed O-ring. Periodically inspect visible connections for signs of wear or corrosion and re-test for leaks after modifications to the loop.
