BitsPower G1/4 Thread Stopper Plugs (4 pcs) — Artemis series, matte black

BitsPower Artemis G1/4 Thread Stopper Plugs are a set of four matte black plugs designed to close unused G1/4 threaded ports in custom water-cooling loops. Manufactured for compatibility with standard G1/4 fittings, each stopper provides a compact, low-profile solution to seal openings on radiators, blocks, reservoirs and fittings, helping to maintain a tidy coolant routing and reduce the risk of accidental leaks during assembly or maintenance.

Advantages

The matte black finish provides a discreet, uniform appearance that integrates with most PC builds without drawing attention. Precision G1/4 threading ensures a snug fit with common water-cooling components while the solid construction delivers reliable sealing for idle ports. Supplied as a pack of four, the set supports multiple spare and maintenance needs, allowing quick closure of several ports at once.

Suitable for

• Sealing unused threaded ports on water-cooling radiators and CPU/GPU blocks
• Closing extra connections on reservoirs and distribution plates
• Temporary sealing during system build, testing or transport
• Spare parts for custom loop maintenance and upgrades

Key specifications

• Thread standard: G1/4 compatible
• Quantity: 4 pieces per pack
• Finish: matte black
• Form factor: low-profile threaded stopper
• Material: metal construction for durable sealing

How to use

Thread the stopper plug into an unused G1/4 port by hand until it seats securely; use light additional tightening with an appropriate tool only if necessary to ensure a leak-free seal. When removing, back the plug out carefully to avoid cross-threading and clean the threads if exposed to coolant. Store unused plugs in a dry place to prevent corrosion and maintain thread integrity for future use.

Recommendations

Before installation, confirm the port uses a G1/4 thread and inspect threads on both the plug and port for damage. For reliable sealing, avoid overtightening; if thread sealant is required, use products compatible with water-cooling systems. Replace any plug that shows signs of wear, deformation or corrosion.
