Fitting Corsair CX-9055019-WW Brass Black Ball Valve Liquid Cooling

The CORSAIR Hydro X Series XF Ball Valve (CX-9055019-WW) is a brass fitting with a black finish designed for PC liquid cooling systems. It integrates a two-stage sealing ball valve that allows you to fully shut off flow for safe draining and maintenance of custom loops.

Advantages

The brass construction provides durability and corrosion resistance, while the two-stage sealing mechanism ensures a reliable, leak-minimizing shutoff. The black finish matches common system aesthetics and the integrated ball valve simplifies draining and flow control without additional adapters.

Suitable for

• Custom PC liquid cooling loops
• Draining and maintenance of radiators, pumps, and reservoirs
• Systems requiring an inline shutoff valve for component replacement

How to use

Install the ball valve in-line with tubing or fittings according to your loop layout and CORSAIR assembly guidance. To drain the loop, rotate the valve to the closed position to stop flow, then open a drain point or reservoir port to release fluid. When finished, return the valve to the open position and verify there are no leaks before powering the system.

Recommendations

Use compatible fittings and tubing sizes, tighten connections to manufacturer torque guidelines, and perform draining and refilling on a stable surface. Inspect seals periodically and replace if wear or damage is observed to maintain leak-free operation.
