## Summary description

BitsPower BP-E90RML is a brass 90° rotary elbow fitting for liquid computer cooling systems. Finished in silver, it uses a 1/4" connecting thread and is designed to route coolant in tight spaces while allowing rotation for easy tube alignment. Suitable for custom water-cooling loops, radiators, pumps and blocks where durable metal fittings are required.

## Long description

BitsPower BP-E90RML is a brass 90° rotary elbow fitting designed for liquid computer cooling systems. Finished in silver, this compact metal fitting features a 1/4" connecting thread and a rotatable joint to help route coolant tubing in constrained or awkward spaces. It is intended for use in custom water-cooling loops where a durable, corrosion-resistant elbow is required to connect radiators, pumps, reservoirs and water blocks while preserving tidy tubing runs and reliable sealing.
Advantages
The brass construction provides mechanical strength and good corrosion resistance compared with many non-metal fittings, while the silver finish offers a neutral appearance that integrates with a variety of system designs. The 90° angle reduces stress on tubing at tight turns and the rotary joint allows final orientation without twisting or kinking the tube. The standard 1/4" thread ensures compatibility with common water-cooling components that accept this thread size.
Suitable for
 Custom PC water-cooling loops that require compact 90° direction changes
 Connections between radiators, pumps, reservoirs and water blocks in tight enclosures
 Systems where a rotatable fitting simplifies tube alignment and installation
 Builds that prefer metal fittings for durability and better long-term sealing
Key specifications
 Material: brass
 Finish: silver
 Angle: 90° rotary elbow
 Thread type: standard 1/4" connecting thread
 Application: liquid cooling for desktop computer systems
How to use
Install the fitting by hand-threading into the mating port and tightening to a secure fit; avoid over-tightening to prevent damage to threads or mating components. Rotate the elbow to the desired orientation before final tightening, ensuring tubing follows a smooth curve without sharp bends or kinks. Use compatible sealing methods or thread tape if required by the mating component's specifications, and verify all connections for leaks after filling the loop and during an initial test run.
Usage recommendations
Inspect mating threads and component manuals for recommended torque or sealing procedures. Combine metal fittings like this brass elbow with appropriate soft tubing or hardline adapters and compatible coolant. Perform a leak test with the system powered off and pump running for several hours before regular operation.
