Cooling system part BitsPower BP-BSWP-C27 — brass, black finish

BitsPower BP-BSWP-C27 — brass, black finish is a precision cooling system part designed for custom PC liquid-cooling loops. Machined from high-quality brass with a black nickel-like finish, this component provides a durable connection point for 3/8" inner-diameter tubing in 90-degree routing applications. The part features a hi-flow geometry and a concealed O-ring seating to reduce flow restriction while maintaining a secure, leak-resistant seal in tight bends and compact builds.

Advantages

The brass construction ensures mechanical strength and corrosion resistance appropriate for long-term water-cooling use, while the black finish offers a uniform appearance that integrates with dark-themed builds. The hi-flow design minimizes flow losses at the 90-degree junction, and the hidden O-ring reduces the risk of external damage to the seal during installation and maintenance. RoHS compliance indicates the component meets common environmental material standards for electronics assemblies.

Suitable for

• Custom PC liquid-cooling loops requiring a 90° fitting for 3/8" ID tubing
• High-flow refrigeration of CPU and GPU blocks in enthusiast and workstation builds
• Maintenance or replacement of metal fittings in existing water-cooling systems

Key specifications

• Material: high-quality brass
• Finish: black nickel-like surface
• Design orientation: 90° elbow for tubing routing
• Tubing compatibility: 3/8" inner diameter (ID)
• Seal type: concealed O-ring
• Flow characteristic: hi-flow geometry for reduced restriction
• Regulatory: RoHS compliant

How to use

Install the fitting into a compatible metal or compression connector according to the manufacturer of your fittings and tubing. Ensure the tubing end is cut square and fully inserted to the seating point so the concealed O-ring forms a reliable seal. Tighten any mating threads evenly to the torque specified by your loop components to avoid overtightening. Check the assembly for leaks during an initial pressure or leak test before powering the system components.

Recommendations

Before final assembly, perform a leak test with non-powered components and use coolant compatible with brass to avoid galvanic or chemical interactions. Periodically inspect connections for signs of wear or corrosion and replace seals as part of routine maintenance to preserve flow performance and sealing integrity.
