Cooling accessory BitsPower BP-DW90R — brass white, dimensions 18×18×31.8 mm

BitsPower BP-DW90R is a compact brass cooling accessory with a white electro-plated finish, designed for tight installation spaces in custom liquid-cooling loops and PC builds. With dimensions of 18×18×31.8 mm, this 90-degree fitting provides a low-profile directional change for tubing or components using a G1/4"-type threaded interface, while its rotatable head allows precise alignment without twisting connected lines or fittings.

Advantages

The accessory combines a hi-flow internal passage with durable brass construction and a white e-plated surface treatment that resists corrosion and maintains appearance. A 360-degree rotation feature enables easy orientation during assembly, and a concealed O-ring design improves sealing reliability while keeping a neat external look. Its compact form factor helps conserve space in dense builds and supports reliable fluid flow in tight routing scenarios.

Suitable for (tasks / use cases)

• Redirecting coolant flow in custom liquid-cooling loops where a compact 90-degree turn is required
• Connections between blocks, radiators, pumps or reservoirs in small or tight PC cases
• Builds that require a white-colored fitting to match or contrast with system aesthetics
• Applications needing a durable brass fitting with reliable sealing and rotatable orientation

Key specifications

• Material: Brass with white electro-plated finish
• Shape: 90-degree angled fitting with rotatable head (360° rotation)
• External dimensions: 18 × 18 × 31.8 mm
• Thread interface: G1/4"-type thread for standard liquid-cooling components
• Flow design: Hi-flow internal passage to reduce restriction
• Sealing: Hidden O-ring sealing design
• Compliance: RoHS compliant

How to use

Ensure mating threads and sealing surfaces on the connected cooling components are clean and free of debris. Hand-start the fitting into the counterpart, then tighten to the recommended torque for G1/4"-type connections using an appropriate tool to avoid over-tightening. Rotate the head to align the outlet orientation as needed before final tightening; the rotatable design permits alignment without twisting tubing. After installation, perform a pressure or leak test according to your system build procedure before powering the PC.

Recommendations

For reliable long-term performance, use compatible lubricants or sealing compounds approved for liquid-cooling systems on O-rings only if specified by the cooling component manufacturers. Avoid excessive torque and inspect O-rings periodically for wear when reconfiguring the loop. Match the fitting finish and size to tubing and component clearances to maintain the intended aesthetic and flow path.
