## Summary description

Singularity SC-STOP-PLUG is a G1/4" brass stop plug designed for use with liquid cooling fittings and threaded ports. The solid brass construction provides corrosion resistance and reliable sealing for unused or service ports in water-cooling loops. Intended for filling, draining, or temporarily closing G1/4" interfaces in PC cooling systems and custom liquid-cooling assemblies.

## Long description

Singularity G1/4" Stop Plug is a brass threaded plug engineered for closing unused or service G1/4" ports in liquid cooling fittings and custom water-cooling loops. The solid brass body offers corrosion resistance and mechanical stability for temporary or long-term sealing of fill, drain, and inspection points in PC liquid-cooling systems. The compact, male G1/4" thread ensures compatibility with the wide range of industry-standard ports and fittings used in radiator, block, and reservoir assemblies.
Advantages
The brass construction provides durable corrosion resistance and dimensional stability under typical PC cooling temperatures. Threaded G1/4" engagement delivers reliable sealing and mechanical retention without adhesives. The plug's smooth external profile minimizes turbulence and allows simple access in tight spaces. Its straightforward design supports repeated installation and removal for maintenance, filling, or leak testing.
Suitable for
Sealing unused G1/4" ports on radiators, water blocks, reservoirs, and fittings
Temporary closure of fill or drain ports during system assembly or transport
Providing leak-free access points during filling and pressure testing of loops
Use in custom liquid-cooling setups where a compact, threaded plug is required
Key specifications
Thread type: G1/4" male threaded plug compatible with standard G1/4" ports
Material: solid brass body for corrosion resistance
Intended use: sealing, filling, draining, and temporary closure of liquid-cooling ports
Compatibility: industry-standard PC water-cooling fittings, radiators, reservoirs, and blocks with G1/4" threads
Form factor: compact, low-profile threaded plug suitable for tight installations
How to use
Inspect the threaded port and plug for debris or damage before installation. Hand-start the plug into the G1/4" female thread, ensuring correct alignment to avoid cross-threading. Tighten the plug securely by hand; if additional torque is required, use an appropriate tool that engages the plug without deforming the brass surface. Do not overtighten beyond a snug fit. For removal, loosen the plug with the same tool or by hand, allowing safe draining or access to the port.
Usage recommendations
For reliable sealing, ensure mating threads are clean and dry; use a small amount of thread sealant or PTFE tape only if a higher degree of leak prevention is needed. Avoid excessive torque to prevent thread damage. Periodically inspect installed plugs during maintenance, especially if used in systems with frequent temperature cycling or aggressive coolant chemistries.
