Computer cooling system part BitsPower BP-MBWP-C42 — brass, black finish

BitsPower BP-MBWP-C42 is a brass component finished in deep black, made for custom PC liquid-cooling systems. The part features a true hi-flow design and dual G1/4" compatibility, allowing integration into a variety of water-cooling assemblies. Brass construction provides mechanical strength and corrosion resistance typical of high-quality metal fittings used in PC cooling loops.

Advantages

The component combines a high-flow internal profile with precision brass machining for consistent fluid movement and long service life. A deep black e-plated finish enhances surface durability and offers a uniform aesthetic for black-themed builds. The hiding O-ring design improves sealing reliability while keeping visible seams minimal. The part is RoHS compliant and intended for repeated installation in maintenance or upgrade scenarios.

Suitable for

• Custom PC water-cooling loops requiring durable metal fittings
• Black-themed builds where matching finish is needed
• Systems that need dual G1/4" connection options or adapters
• Upgrades or replacements of existing brass cooling components

Key specifications

• Material: brass
• Finish: deep black e-plated coating
• Flow design: true hi-flow internal profile
• Connection: dual G1/4" application
• Seal: hiding O-ring design for improved aesthetics and leak prevention
• Compliance: RoHS compliant

How to use

Install the part into the cooling loop using standard G1/4" fittings or ports. Ensure mating threads are clean and apply the appropriate O-rings if not preinstalled; the hiding O-ring design should seat into its groove for a proper seal. Tighten by hand and finish with a small wrench turn if required, taking care not to overtighten brass threads. After installation, perform a pressure or leak test with coolant to validate sealing before powering any components.

Recommendations

Use corrosion-resistant coolant formulations and follow the system manufacturer's maintenance intervals. When working with brass fittings, avoid excessive torque to preserve thread integrity and the protective e-plated finish; periodic inspection during maintenance will help detect early signs of wear or leakage.
