Fitting BitsPower BP-DWE90RMLA14 — brass 90° rotary fitting, diameter 1.4 cm, white

BitsPower BP-DWE90RMLA14 is a 90° rotary fitting made from brass with a white coated finish and a 1.4 cm external diameter, engineered for custom PC liquid cooling loops. The fitting enables compact angled connections between tubing and components such as radiators, reservoirs and pump outlets, allowing tubing to be routed more efficiently while reducing mechanical stress on joints. Its rotary feature permits orientation adjustment during installation to achieve precise alignment without twisting tubing or other fittings.

Advantages

The brass construction provides durability and corrosion resistance appropriate for water-cooling environments, while the white coating offers a consistent aesthetic to match white or light-themed builds. The 90° angle reduces the need for long tube runs and tight bends, improving flow path neatness and simplifying component placement. The rotary function eases installation by allowing the fitting to be rotated to the desired position after tightening, minimizing torque transmitted to connected components.

Suitable for

• Custom PC water-cooling loops where angled connections are required
• Connections to radiators, reservoirs and pump outlets with limited clearance
• Systems that require tidy tubing routing and reduced joint stress
• Builds with white or light-coloured aesthetics

Key specifications

• Material: brass with white coating
• Angle: 90° rotary
• External diameter: 1.4 cm
• Finish: white-coated surface
• Function: swivel/rotating joint for orientation adjustment

How to use

Install the fitting by attaching it to the corresponding threaded port on the component (radiator, reservoir or pump) and tighten by hand or with an appropriate wrench until snug, taking care not to over-tighten. Connect tubing of matching internal diameter over the barb or compression collar as applicable, ensuring a secure seal with clamps or compatible compression fittings. After securing the connection, rotate the fitting to achieve the optimal tubing orientation before completing final torque. Perform a leak test on the filled loop at low pressure or by running the pump with power only to the cooling system components.

Recommendations

Use tubing and sealing methods that match the fitting diameter and material compatibility. Avoid excessive mechanical stress by allowing the rotary fitting to be aligned rather than bending tubing sharply. Periodically inspect fittings for signs of wear or coating damage and check for leaks after initial operation and during routine maintenance.
