Computer cooling system accessory BitsPower BP-MBRG brass fitting, black finish

BitsPower BP-MBRG brass fitting in black finish is a precision accessory for PC liquid cooling systems. Manufactured from high-quality brass with a deep black e-plated surface, it is intended for use in custom water-cooling loops to provide robust, corrosion-resistant connections between tubing, water blocks, radiators and pumps. The fitting features a true hi-flow profile and a concealed O-ring design for reliable sealing and a neat appearance while allowing full 360-degree rotation for flexible hose routing.

Advantages

The brass construction delivers improved durability and resistance to corrosion compared with many plated alloys, while the deep black e-plated finish offers consistent appearance and surface protection. The true hi-flow internal design reduces flow restriction in liquid cooling loops. A hidden O-ring improves leak protection without exposed rubber, and the full 360-degree rotation simplifies installation and alignment of tubing runs in tight or complex builds. The fitting is manufactured to meet RoHS requirements.

Suitable for

• Custom PC water-cooling loops for CPUs and GPUs
• Connections between tubing and water blocks, radiators or pumps
• High-flow systems where reduced hydraulic resistance is needed
• Metal-fitting builds requiring durable, long-lasting components

Key specifications

• Material: High-quality brass
• Finish: Deep black e-plated surface
• Flow characteristic: True hi-flow internal profile
• Rotation: Full 360-degree swivel capability
• Seal design: Concealed O-ring for leak protection
• Compliance: RoHS compliant

How to use

Install the fitting by threading it into the appropriate port on a water block, radiator or pump, ensuring the concealed O-ring seats correctly to form a tight seal. Attach the compatible tubing over the barbed or compression portion (depending on the exact fitting variant) and secure according to your tubing type—use clamps or compression rings where required. The 360-degree rotation allows you to orient the tubing for optimal routing before final tightening. Verify all connections for proper alignment and perform a leak test before powering the system.

Recommendations

For long-term reliability, use compatible coolant and regularly inspect fittings during maintenance intervals. Tighten fittings to manufacturer-recommended torque ranges for your build, avoid over-tightening which can damage threads or O-rings, and perform a slow pressure or leak test after filling the loop. When assembling, ensure tubing inner diameter and fitting interface match to maintain the hi-flow characteristics.
