CPU water block accessory BitsPower BP-MBWP-C11, brass construction, black finish

BitsPower BP-MBWP-C11 is a brass-constructed CPU water block accessory finished in deep black, designed for custom liquid cooling loops. It functions as a component to route coolant and interface with tubing and fittings, offering mechanical durability and corrosion resistance typical of brass materials. The piece is intended for integration into CPU cooling assemblies or other water-cooled components where reliable coolant flow and secure sealing are required.

Advantages

The accessory features a hi-flow internal design to promote efficient coolant movement and help maintain lower temperatures across the loop. Manufactured from high-quality brass and treated with a durable e-plated deep black finish, it resists wear and provides a consistent surface for sealing. A hidden O-ring arrangement improves the aesthetic appearance and ensures reliable leak prevention when used with compatible tubing and fittings. The part is RoHS compliant and engineered specifically for tubing with an inner diameter of 8 mm and an outer diameter of 10 mm.

Suitable for

• Custom CPU liquid cooling loops in desktop PCs
• Integration with water blocks, radiators, pumps, and reservoir assemblies
• Systems using soft tubing with 8 mm ID / 10 mm OD
• Upgrades or replacements in brass-compatible cooling setups

Key specifications

• Material: Brass construction
• Finish: Deep black e-plated surface
• Internal flow: Hi-flow design for improved coolant movement
• Tubing compatibility: Designed for 8 mm inner diameter / 10 mm outer diameter tubing
• Sealing: Hidden O-ring design for leak prevention
• Environmental compliance: RoHS compliant

How to use

Install the water block accessory as part of a closed-loop liquid cooling system by connecting it to compatible fittings and tubing that match the specified 8 mm ID / 10 mm OD dimensions. Ensure tubing ends are cut squarely and pushed fully over the sealed connection point so the hidden O-ring seats correctly. Tighten any compression fittings or clamps to the manufacturer’s recommended torque to secure the joint without over-compressing the tubing. Confirm alignment within the loop to prevent kinks and maintain optimal flow paths.

Recommendations

Before filling the loop, perform a pressure or leak test with plain water or a non-conductive coolant to verify all connections are secure. Use compatible soft tubing of the specified dimensions and check O-ring condition during routine maintenance. Avoid aggressive chemicals that may degrade plating or brass; follow coolant manufacturer guidance for long-term corrosion protection.
