## Summary description

BitsPower BP-E90RMLA12 is a brass tubing component for computer liquid cooling systems. It has a 12 mm external diameter and a silver finish, suitable for use as rigid or connector tubing in custom loops, radiators, and block connections. Designed to provide durable fluid passage and corrosion resistance in PC water-cooling assemblies.

## Long description

BitsPower BP-E90RMLA12 is a brass tubing component intended for use in computer liquid cooling systems. With a 12 mm external diameter and a silver finish, this part is designed to function as rigid tubing or as a connector between hard tubes, radiators and cooling blocks. Constructed from high-quality brass and finished for corrosion resistance, it supports durable fluid passage in custom PC water-cooling loops while maintaining a compact profile for tight assemblies.
Advantages
The brass construction offers mechanical strength and improved corrosion resistance compared with some base metals, while the silver finish provides a neutral aesthetic that integrates with a wide range of system builds. The design simplifies installation with hard tubes by providing a secure mating surface for OD12 mm tubing, and when assembled correctly the fittings hold connections firmly to reduce the risk of leaks. The component is RoHS compliant and engineered for multi-link extension use in modular cooling configurations.
Suitable for
 Custom PC water-cooling loops using 12 mm OD rigid tubing
 Connecting radiators, pumps and water blocks where a short brass connector is required
 Systems requiring corrosion-resistant metal fittings
 Modular or multi-link extension applications in compact cases
Key specifications
 Material: high-quality brass
 External diameter: 12 mm (designed for OD12 mm hard tubing)
 Finish: silver
 Intended use: rigid tubing connector for PC liquid cooling
 Compliance: RoHS
How to use
Prepare matching OD12 mm hard tubes by cutting and deburring the ends to ensure a clean, square seat. Slide the tubes into the connector until fully seated and secure the connection with the appropriate compression or clamping fittings designed for OD12 mm rigid tubing. Verify alignment between the connected components (radiator, block, pump) to avoid axial stress. After assembly, perform a pressure or leak test with non-conductive coolant before powering the system to confirm a watertight seal.
Usage recommendations
Use only compatible OD12 mm hard tubing and recommended compression fittings. Ensure all tube ends are smooth and free of burrs before installation, and always perform a leak test with the system powered off. For long-term reliability, periodically inspect fittings and coolant for signs of corrosion or degradation.
