Cooling system accessory BitsPower BP-BSE90DML brass fitting for PC liquid cooling

BitsPower BP-BSE90DML brass fitting for PC liquid cooling is a 90-degree connector engineered to integrate tubing, blocks, radiators and pumps within custom water-cooling loops. Constructed from brass with a nickel finish in black sparkle, this fitting aims to provide a durable, corrosion-resistant junction that maintains coolant flow while minimising the risk of leaks. The component features a true hi-flow internal geometry and is developed for dual multi-link extension via crystal link tube on both sides, making it suitable for compact routing and tight installations.

Advantages

The brass construction offers high mechanical strength and corrosion resistance, while the nickel black sparkle finish improves surface protection and aesthetic compatibility with many system builds. The true hi-flow design reduces flow restriction compared with more restrictive elbow fittings. Its 90-degree orientation facilitates neat cabling of tubing in confined spaces and supports dual multi-link extension using crystal link tubes at both ends. The fitting is RoHS compliant, indicating conformance with common material safety requirements.

Suitable for

• Custom PC water-cooling loops with 90-degree routing needs
• Connections between tubing, water blocks, radiators and pumps
• Compact or densely packed PC cases where angled fittings simplify tubing runs
• Builds using crystal link tube extensions or dual-link configurations

Key specifications

• Material: brass body with nickel-plated black sparkle finish
• Orientation: 90-degree elbow type
• Flow characteristic: true hi-flow internal design to minimise restriction
• Application: dual multi-link extension compatibility via crystal link tube on both sides
• Durability: high mechanical strength and corrosion resistance suitable for long-term coolant exposure
• Compliance: RoHS compliant

How to use

Install the brass fitting by seating tubing or crystal link sections onto each side and tightening according to the tubing or compression ring requirements of your loop components. Ensure mating threads or compression collars are clean and properly aligned before tightening to achieve a leak-resistant connection. When routing tubing, use the 90-degree orientation to guide hoses along case panels or around components, avoiding sharp bends that could kink soft tubing. After assembly, perform a pressure or leak test with coolant or recommended testing fluid prior to full system operation.

Recommendations

Use compatible tubing and compression fittings sized to the same inner/outer diameters to ensure correct sealing. During initial filling and testing, run the pump at lower speed and inspect all connections for seepage. Periodically check fittings for tightness and signs of corrosion or wear, and replace components showing degradation to maintain system integrity.
