Alphacool 17198 G1/4" HF Stop Plug Fitting Deep Black

G1/4 Inch Stop Plug for Water Cooling

This Alphacool G1/4 inch stop plug seals unused ports on radiators, reservoirs and other liquid cooling components. The Deep Black finish matches dark themed builds for a uniform appearance. It is a simple screw in fitting designed to close off open threads cleanly. Model 17198 provides a reliable seal for custom loop maintenance or layout changes.

Thread Compatibility and Sealing Limits

The fitting uses a standard G1/4 inch thread common in PC water cooling hardware. It fits any component with a matching female G1/4 port such as radiators, pump tops or distribution plates. The plug relies on an integrated seal to prevent leaks when tightened correctly. It does not function as a flow control valve or a pass through coupling for tubing connections.

Replaces Open Ports and Mismatched Colours

This plug upgrades a build by replacing exposed open ports or chrome coloured plugs that break a black colour scheme. The jump is worth it when finishing a custom loop where every visible fitting shares the same Deep Black tone. It is not for builders who need a pass through fitting to connect tubing between components. Nor does it suit systems using non G1/4 thread standards.
