Cooling accessory BitsPower BP-MB90R2 brass right-angle adapter, black, 18×29×39.8 mm

BitsPower BP-MB90R2 brass right-angle adapter in black is a compact cooling accessory designed for liquid-cooled PC systems. With dimensions of 18 × 29 × 39.8 mm and a right-angle configuration, this adapter helps route tubing and connect fittings in tight spaces while maintaining a high flow rate. Constructed from brass with an e-plated deep black finish and featuring a concealed O-ring layout, the adapter is intended for custom water-cooling loops that require a robust, low-profile angled connection.

Advantages

The adapter combines a true hi-flow internal design with high-quality brass construction to provide durable, corrosion-resistant performance and stable coolant circulation. Dual 360-degree rotation allows flexible orientation without compromising the seal, while the e-plated black finish offers a consistent appearance and additional surface protection. The hidden O-ring design reduces visible seals and helps maintain a clean routing aesthetic in compact builds.

Suitable for

• Custom PC water-cooling loops where space constraints require a compact right-angle connection
• Tight or small-form-factor cases that need tubing routed at 90-degree angles
• Connections between blocks, radiators, pumps, and reservoirs with matching thread/type
• Builds that require rotational adjustment to align fittings without twisting tubing

Key specifications

• Finish: E-plated deep black
• Type: 90-degree right-angle adapter with dual 360-degree rotation
• Design feature: Hidden O-ring sealing
• Flow characteristic: True hi-flow internal pathway
• Compliance: RoHS compliant
• Dimensions (approx.): 18 × 29 × 39.8 mm

How to use

Install the adapter by first ensuring mating threads and sealing surfaces on the other fitting or component are clean and dry. Hand-tighten the adapter onto the corresponding fitting or port, then make final alignment using the dual rotation capability to orient the outlet at the desired angle. Do not overtighten; use appropriate tools only if required and follow the torque guidance of the connected components. After assembly, pressure-test the loop or perform a leak check before powering the system.

Recommendations

Use this right-angle adapter in conjunction with compatible brass or plated fittings to avoid galvanic mismatch. For best results in compact builds, route tubing with gentle bends and allow room for the adapter’s rotational adjustment. Regularly inspect O-ring seals during maintenance and replace them if worn to maintain leak-free operation.
