CPU/GPU liquid cooling fitting BitsPower BP-MBE90RML brass 90° rotary adapter 1/4 inch thread black

Bitspower BP-MBE90RML is a brass 90° rotary adapter designed for custom liquid cooling loops in desktop PCs. Finished in black, this compact fitting accepts a 1/4" (G1/4) threaded connection and provides an angled interface between tubing, blocks, radiators or other components. The rotatable joint allows precise alignment without twisting hoses, helping to route coolant lines neatly in confined spaces around CPU and GPU blocks.

Advantages

The brass construction ensures corrosion resistance and reliable mechanical strength for long-term use in water-cooling systems. The 90° angle reduces hose bending and stress at connection points, while the rotary capability enables fine orientation for tight builds. The black finish offers a neutral appearance that integrates with a wide range of system aesthetics.

Suitable for

• Custom PC liquid cooling loops where space is limited
• Connecting tubing to CPU and GPU water blocks at tight angles
• Orienting fittings to reduce hose strain and improve coolant flow path
• Upgrading or replacing angled connections in radiator or pump lines

Key specifications

• Material: brass
• Finish: black coating
• Angle: 90°
• Rotary: yes, swivel joint for alignment
• Thread type: 1/4" (G1/4) female/male-compatible connection
• Application: liquid cooling fittings for PC components

How to use

Install the adapter into a compatible threaded port on a water block, radiator or other component by hand-tightening and then securing with a suitable wrench if required, taking care not to over-torque. Attach tubing or a compatible barb/adapter to the opposite side and rotate the swivel section to orient the outlet to the desired direction before final tightening. Verify that seals are seated correctly and perform a leak test with the loop filled but the system powered off.

Recommendations

Use appropriate sealing washers or PTFE tape on threaded connections if recommended by other components in your loop; avoid excessive force when tightening to prevent thread damage. Regularly inspect fittings for signs of wear or corrosion and re-check fittings after the initial leak test and first few hours of operation.
