Alphacool distribution adapter ES 2xMCX for 12.7/7.6 mm tubing with barbed brass fittings (14645)

Alphacool distribution adapter ES 2xMCX for 12.7/7.6 mm tubing with barbed brass fittings is a metal fluid-routing component intended for water-cooling and custom liquid loop systems. The adapter features two MCX connections and barbed ends sized for secure interfacing between 12.7 mm (outer diameter) and 7.6 mm tubing. Constructed from brass, it is designed to offer mechanical strength, corrosion resistance, and reliable sealing when used with appropriate tubing and clamps in PC cooling or small-scale fluid distribution setups.

Advantages

The brass construction provides improved durability and resistance to wear compared with many plastic fittings while maintaining a compact footprint suitable for tight installations. Barbed ends create a firm mechanical grip on tubing, reducing the risk of accidental disconnection under normal operating pressures. The two-way MCX distribution layout allows splitting or joining of flows in custom loops and simplifies routing in confined spaces. The straightforward design requires minimal maintenance and can be used for repairs or system expansions.

Suitable for

• Custom PC water-cooling loops and radiator connections
• Small fluid distribution or routing tasks in electronics cooling
• Repairing or modifying existing tubing runs with 12.7 mm and 7.6 mm hoses
• Hobbyist and laboratory setups requiring compact metal fittings

Key specifications

• Material: brass
• Connection type: barbed fittings with MCX distribution layout
• Compatible tubing sizes: 12.7 mm and 7.6 mm (outer diameter)
• Function: split or join fluid lines in liquid-cooling systems
• Surface finish: metallic (untreated brass appearance)

How to use

Ensure tubing and system are depressurized and drained before installation. Slide the correct diameter tubing onto each barbed end fully so the tubing covers the barb ridges; use suitable clamps or hose clips to secure each connection and prevent leaks. Position the adapter to minimize stress and bending on connected hoses. After assembly, refill the loop, run a controlled leak test at operating pressure, and inspect all connections for seepage. If corrosion or damage is observed, replace the fitting to maintain system integrity.

Usage recommendations

Use corrosion-inhibiting coolant compatible with brass and avoid prolonged exposure to aggressive chemicals. Select hose clamps sized for the tubing diameters and tighten evenly to avoid deforming the tubing. Regularly inspect fittings during maintenance intervals and replace if threads or barbs show signs of wear or corrosion.
