PHANTEKS G1/4 inch Chrome Plated Brass Stop Plug

When building a custom water cooling loop, every port must be sealed with confidence. The PHANTEKS G1/4" Stop Plug delivers a secure, leak-proof closure for unused ports on reservoirs, radiators, pumps, and blocks. Machined from solid brass and finished with a mirror-like chrome plating, it combines durability with a clean, professional look that matches Phanteks' premium cooling hardware. Unlike generic plastic plugs, this plug resists corrosion and maintains thread integrity over repeated installations.

Highlights

• Precision G1/4" BSPP threads for universal compatibility
• Solid brass construction with chrome plating for corrosion resistance
• Integrated O-ring seal (NBR) ensures a reliable, leak-free fit
• Knurled grip allows easy hand-tightening without tools
• Low-profile design fits in tight spaces

In daily use

Installing the plug is straightforward: ensure the port is clean, place the O-ring against the sealing surface, and hand-tighten until snug. The knurled edge provides a firm grip, even with wet fingers. Because the plug is made of brass, it won't strip or crack like plastic alternatives, and the chrome finish resists tarnishing. Whether you're sealing a spare port on a multi-port radiator or closing off an unused inlet on a pump top, this plug keeps your loop clean and leak-free.
