Fitting Corsair CX-9055017-WW

The CORSAIR Hydro X Series XF Fill Port Adapter (MPN CX-9055017-WW) is a brass G1/4" fitting with a chrome finish designed for custom PC liquid cooling loops. It provides a dedicated fill and drain point for the cooling system and includes a G1/4" stopper plug to seal the port when not in use. Made from durable brass, the adapter offers a secure, leak-resistant connection and a polished look that complements modern PC builds.

Advantages

The Chrome-plated brass construction delivers durability and corrosion resistance while the integrated G1/4" stop plug simplifies filling and draining operations. Its compact design fits standard G1/4" ports commonly used in liquid cooling setups, ensuring compatibility and a reliable, watertight seal. The adapter's finish also provides a clean visual match with other metal fittings in the system.

How to use

Install the adapter into any standard G1/4" threaded port on a radiator, reservoir, or tubing component by hand-tightening and then securing with a wrench if needed—avoid overtightening. Remove the included stopper plug to fill or drain the loop, and replace the plug to seal the port after the operation. Ensure system power is off and pressure is relieved before opening the loop to prevent spills or damage.

Recommendations

Use compatible G1/4" fittings and standard coolant. Inspect seals and threads for wear during maintenance and replace the stopper plug if it shows signs of degradation. Tighten fittings snugly but do not over-torque to avoid damaging threads or deformation of the fitting.
