Cooling system accessory BitsPower BP-BSWP-C04 — brass construction, black finish

BitsPower BP-BSWP-C04 is a brass cooling system accessory with a black finish designed for integration into custom water-cooling loops and cooling assemblies. The component combines a durable brass construction with a high-quality black surface treatment and a sealed O-ring to provide reliable sealing and long-term corrosion resistance. Its hi-flow design supports unrestricted liquid passage, making it suitable as a functional fitting or a visual accent in PC water-cooling builds.

Advantages

The accessory is manufactured from high-quality brass, providing mechanical strength and natural resistance to corrosion. A black sparkle finish delivers consistent aesthetics for dark-theme builds while the hi-flow internal profile minimizes flow restriction. The included sealed O-ring ensures a leak-resistant connection for through-hole applications. RoHS compliance confirms that the part meets common material safety standards for electronic assemblies.

Suitable for

• Custom PC water-cooling loops and radiator connections
• Through-hole fittings in cooling panels and reservoirs
• Builders seeking a black metal accent or durable fitting
• Replacement or upgrade of existing brass fittings

Key specifications

• Material: Brass construction
• Finish: Black sparkle surface treatment
• Design: Hi-flow internal profile
• Sealing: Included sealed O-ring for leak resistance
• Application type: Through-hole installation
• Compliance: RoHS compliant

How to use

Install the fitting into the intended through-hole location on a panel, reservoir or chassis port designed for liquid-cooling connections. Ensure the O-ring is properly seated before inserting the part and tighten to the recommended torque for your system to avoid overtightening. Verify alignment with tubing or mating components and check for leaks after filling the loop. Periodic inspection during maintenance will help ensure long-term sealing and performance.

Recommendations

Use compatible tubing and compression fittings designed for water-cooling systems and follow manufacturer guidance on assembly torque. During initial system fill, perform a leak test at low pressure and run the pump with no power to other components when possible. For longevity, avoid aggressive or incompatible coolant additives and inspect the O-ring periodically for wear or degradation.
