## Summary description

BitsPower BP-MBWP-C21 is a computer cooling system part made from brass with a black finish. Designed for use in water-cooling loops and custom liquid-cooling setups, this accessory provides durable metal construction and corrosion resistance typical of brass components. Suitable for PC builders and maintenance when replacing or upgrading cooling hardware.

## Long description

BitsPower BP-MBWP-C21 is a brass computer cooling system part with a deep black e-plated finish, designed for use in custom water-cooling loops. Built from high-quality brass and finished with corrosion-resistant plating, this component provides durable metal construction and a concealed O-ring seal for reliable leak prevention. The part features a high-flow geometry in a G3/8" threaded form factor and is compatible with specified pump inlet and outlet orientations in custom liquid-cooling assemblies.
Advantages
The brass construction offers strength and corrosion resistance while the e-plated deep black surface provides chemical protection and a consistent aesthetic for black-themed builds. The extreme-flow internal design reduces hydraulic resistance in a G3/8" threaded application, supporting efficient coolant circulation. A hiding O-ring design improves sealing reliability and presents a cleaner exterior appearance compared with visible-mounted seals.
Suitable for
Custom PC water-cooling loops requiring G3/8" threaded metal fittings
Replacement or upgrade of fittings on compatible pump inlet and outlet ports
Enthusiast builds with a black finish or metal hardware preference
Systems where corrosion resistance and long-term durability are priorities
Key specifications
Material: high-quality brass
Finish: deep black e-plated coating
Thread type: G3/8"
Flow design: extreme/high-flow internal geometry
Seal: concealed O-ring sealing design
Compliance: RoHS compliant
How to use
Install the fitting into the matching G3/8" threaded port of your water-cooling loop or pump inlet/outlet. Ensure the mating thread and port are clean and free of debris, then hand-start the thread to avoid cross-threading before fully tightening with appropriate tools. Verify the concealed O-ring is seated correctly to achieve a watertight seal. After installation, perform a pressure or leak test with coolant or a suitable substitute before powering the PC to confirm there are no leaks.
Usage recommendations
Use with compatible G3/8" threaded tubing and pump ports, and avoid overtightening to protect threads and O-ring integrity. For long-term corrosion protection, periodically inspect fittings and coolant quality; replace the O-ring if signs of wear are present. Follow standard water-cooling maintenance practices, including regular coolant changes and system inspections.
