Computer cooling system part BitsPower BP-BSWP-CT — brass, black finish

BitsPower BP-BSWP-CT is a brass component with a black finish designed for custom PC liquid cooling loops. Intended as a stop fitting with an integrated temperature-sensing option, this metal part provides corrosion resistance and mechanical strength typical of brass hardware. The black sparkle nickel finish improves surface durability while matching common water-cooling aesthetics and metal fittings used in modern builds.

Advantages

The part features a true hi-flow design that maintains coolant throughput in tight loop layouts, while high-quality brass construction ensures long-term reliability and resistance to electrochemical degradation. A hiding O-ring design reduces exposed sealing elements for a cleaner appearance and improved sealing protection. The black nickel sparkle finish enhances scratch resistance and offers a uniform look when paired with other black metal fittings. RoHS compliance confirms the product meets common material safety standards.

Suitable for

• Custom PC water-cooling loops requiring metal stop fittings
• Integration with water blocks, reservoirs or pump tops where compact fittings are needed
• Installations that include temperature monitoring at a stop fitting location
• Builds seeking a consistent black metal aesthetic across cooling hardware

Key specifications

• Material: Brass base construction for corrosion resistance and durability
• Finish: Black sparkle nickel finish for enhanced surface protection
• Flow design: Hi-flow internal geometry to minimise restriction
• Seal design: Hidden O-ring arrangement to protect sealing surface and improve appearance
• Function: Stop/plug fitting compatible with temperature sensor placement
• Standards: Manufactured to meet RoHS material restrictions

How to use

Install the fitting into the designated thread on a block, reservoir or tubing adapter according to the system manufacturer’s recommended torque values. Ensure the O-ring is seated correctly before tightening to prevent leaks. If using the stop fitting as a temperature-sensing point, place the temperature probe or sensor element in the intended recess or mounting interface provided by the fitting, following the sensor manufacturer’s instructions for secure connection. After installation, perform a full leak test at operating pressure or with a leak-testing method appropriate for the loop.

Recommendations

Use compatible thread sealant or PTFE tape only where recommended by the component or system manufacturer; avoid over-tightening to prevent damage to threads or compressing the hidden O-ring excessively. Periodically inspect metal fittings and seals during maintenance intervals to ensure continued sealing integrity and monitor for any signs of galvanic corrosion when dissimilar metals are present in the loop.
