Pump top / reservoir adapter BitsPower BP-MBWP-C01, brass, black finish

BitsPower BP-MBWP-C01 pump top / reservoir adapter is a brass accessory with a deep black finish designed for custom PC liquid-cooling loops. It connects pump and reservoir units to create a reliable, leak-resistant junction while improving coolant routing and overall system neatness. The adapter features a high-flow internal geometry and concealed O-ring sealing to maintain stable flow and a clean external appearance.

Advantages

The adapter is manufactured from high-quality brass with an e-plated deep black surface for corrosion resistance and long service life. Its true hi-flow design reduces turbulence and helps preserve pump performance. The hidden O-ring design minimizes visible seals and simplifies installation while maintaining leak prevention. RoHS compliance ensures the adapter meets environmental and material safety standards.

Suitable for

• Custom PC water-cooling systems requiring a pump-to-reservoir connection
• Upgrades where improved coolant routing and cleaner internal layout are desired
• Systems that demand durable fittings with corrosion-resistant finishes

Key specifications

• Material: brass
• Finish: deep black e-plated coating
• Design: true high-flow internal geometry
• Sealing: concealed O-ring interface
• Compliance: RoHS

How to use

Install the adapter between the pump outlet and the reservoir inlet according to the pump and reservoir manufacturer’s mounting recommendations. Ensure mating surfaces are clean and the concealed O-ring is seated correctly before tightening. Hand-tighten fittings initially, then secure to the required torque to avoid over-compression of seals. After installation, perform a pressure or leak test with the loop filled to verify sealing and correct flow direction.

Recommendations

For optimal results, pair this brass adapter with compatible pump and reservoir ports of matching thread and diameter. Inspect the O-ring periodically and replace if you notice wear or deformation. When assembling, avoid excessive force on fittings and follow standard coolant-handling precautions to prevent contamination.
