Computer Cooling Part BitsPower BP-BSWP-C11J — Brass Black Fitting for Liquid Cooling

BitsPower BP-BSWP-C11J is a brass black fitting designed for custom PC liquid cooling systems. Manufactured from high-quality brass with a black nickel sparkle finish, this fitting creates durable, corrosion-resistant connections between tubing and cooling components. Its Hi-Flow design and concealed O-ring ensure effective flow and leak protection in desktop water-cooling loops, intended for tubing with an inner diameter of 8 mm and outer diameter of 11 mm.

Advantages

The Hi-Flow profile reduces flow restriction and supports efficient coolant circulation, while the brass construction provides mechanical strength and corrosion resistance suitable for long-term use. The black nickel sparkle finish offers wear resistance and a consistent appearance in black-themed builds. A hiding O-ring design improves sealing reliability and visual neatness by keeping the sealing element out of sight.

Suitable for

• Custom desktop PC water-cooling loops
• Connections between radiators, reservoirs, pumps and water blocks
• 8 mm ID / 11 mm OD soft tubing applications
• System builds requiring corrosion-resistant metal fittings

Key specifications

• Material: high-quality brass
• Finish: black nickel sparkle
• Design: Hi-Flow
• Sealing: concealed O-ring
• Compatible tube size: 8 mm inner diameter / 11 mm outer diameter
• Compliance: RoHS compliant

How to use

Install the fitting by sliding compatible 8 mm ID / 11 mm OD soft tubing over the barb until it engages the concealed O-ring, ensuring a snug fit. Tighten any matching compression rings or secure the tubing with appropriate clamps if used in your loop design. Position the fitting between cooling components such as radiators, pumps, reservoirs or water blocks according to your loop layout, and verify correct orientation to maintain optimal coolant flow.

Recommendations

Before first use, inspect the fitting and O-ring for damage and clean contact surfaces. Use compatible coolant and tubing materials to avoid chemical interaction. During initial system fill, check connections for leaks and retighten as needed. Periodically inspect fittings as part of routine maintenance to ensure long-term reliability.
