Bitspower BP-BSE90RML brass 90° rotary fitting for liquid PC cooling, G1/4 thread, black

Bitspower BP-BSE90RML brass 90° rotary fitting is designed for custom liquid PC cooling loops where space and tubing routing are critical. Machined from brass with a black finish, this fitting provides a right-angle connection with a G1/4 thread, while the rotary joint enables smooth alignment of tubing and reduces strain on fittings and blocks. The compact profile helps achieve clean, low-profile runs behind motherboards, radiators, and pump-reservoir assemblies in desktop and workstation systems.

Advantages

The brass construction ensures durability and corrosion resistance in coolant environments, and the black finish offers a discreet appearance that matches most build styles. The 90° angle combined with a rotary mechanism simplifies installation in tight spaces and allows precise orientation of tubing without twisting lines. The use of a common G1/4 thread makes the fitting compatible with a wide range of water-cooling components and adapters.

Suitable for

• Custom desktop and workstation liquid cooling loops
• Tight or compact PC cases where a right-angle connection is required
• Routing tubing around radiators, pump-reservoirs, and water blocks
• Systems requiring neat tubing runs and reduced mechanical stress on connections

Key specifications

• Material: brass
• Finish: black
• Angle: 90° rotary
• Thread type: G1/4 (1/4" BSPP compatible)
• Use: liquid PC cooling fittings for tubing connections and routing

How to use

Install the fitting by threading it into a compatible G1/4 port on a radiator, block, pump, or reservoir. Hand-tighten initially and then secure with a wrench if necessary, avoiding overtightening to prevent damage to threads or mating components. Rotate the joint to orient the outlet at the desired angle and align tubing for a smooth, strain-free connection. Use appropriate sealing or thread tape only if recommended by the component manufacturer.

Recommendations

For reliable long-term operation, inspect fittings and tubing connections during initial system filling and periodically thereafter. Use coolant fluids and additives that are compatible with brass to minimize corrosion and deposits. When working in very tight spaces, support tubing to avoid placing continuous torque on the fitting’s rotary joint.
