Barrow Kepler Plug G1/4 inch THODT-V1 - WS Silver — port plug, G1/4 inch thread, silver finish

Barrow Kepler Plug THODT-V1 - WS Silver is a G1/4" threaded port plug designed for PC water-cooling systems and compatible fittings. The silver-finish plug provides a sealed closure for unused ports to prevent leaks and maintain system integrity. It is suitable for blocking radiator, reservoir or block ports and offers an easy, compact solution for neat installation and safe operation.

Advantages

The Kepler plug features a standardized G1/4" thread for compatibility with common water-cooling components. Its silver finish offers a neutral appearance that integrates with a variety of builds. The plug creates a secure, sealed closure to reduce the risk of fluid leakage and helps preserve system pressure and cleanliness. The compact design allows installation in tight spaces and on crowded manifolds or radiators.

Suitable for

• Sealing unused ports on radiators in custom liquid-cooled PCs
• Closing spare inlet/outlet ports on reservoirs
• Blocking ports on water blocks and distribution manifolds
• Temporary or permanent port sealing during system assembly or maintenance

Key specifications

• Thread type: G1/4"
• Finish color: silver
• Product type: port plug for water-cooling systems
• Compatibility: fittings and components with G1/4" threaded ports
• Form factor: compact, low-profile plug

How to use

To install, align the plug with the G1/4" threaded port and rotate clockwise by hand until it seats. If necessary, use a suitable tool to gently tighten the plug until it is snug; avoid excessive torque to prevent damage to threads or component housings. To remove, rotate counterclockwise and withdraw the plug. Ensure the system is drained or pressure-relieved before installing or removing plugs in a filled loop.

Recommendations

Before installation, inspect threads on both the plug and the target port for debris or damage. For repeated installations or where additional sealing is required, consider using an appropriate thread sealant or tape compatible with PC water-cooling fluids. Do not overtighten; follow component manufacturer guidance for recommended torque where provided.
