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.

Questions about this item

Should I choose the Chrome or Deep Black version of the Alphacool 17198 stop plug?

Choose Deep Black to match other black fittings in your loop, or Chrome for a contrasting metallic highlight; both share the same G1/4 thread and sealing performance.

What does the G1/4 thread mean when I install this plug in my radiator or reservoir?

It screws directly into any standard G1/4 female port on radiators, reservoirs or blocks, sealing the unused opening without adapters.

How does the G1/4 thread standard limit where this stop fitting can be used?

It only fits components with G1/4 female threads; it will not work on NPT, metric or proprietary ports without a separate adapter.
