- Sealed with a rubber O-ring
Who it fits
Good fit for
You should consider this plug if you are building a custom loop and need to cap off unused ports on pumps, reservoirs, or radiators. The G1/4" thread ensures it fits standard fittings. The brass construction offers durability, while the satin titanium finish matches high-end EK Quantum components. If you want to keep dust out of empty ports and maintain a clean aesthetic, this plug provides a secure, sealed solution for your system.
Who should skip it
You should look at another option if you need a plug with a different thread size, as this unit is strictly G1/4". It is also not suitable if you require a transparent plug to check for liquid leaks, as the brass and titanium construction is opaque. Additionally, if you prefer a plastic or aluminum finish over the satin titanium look, this specific model may not match your aesthetic preferences. The 23mm diameter is fixed, so do not expect adjustable sizing.
Verdict: This plug offers a durable, sealed solution for capping unused G1/4" ports. Its brass construction and titanium finish make it a solid choice for maintaining a clean, dust-free custom loop.
Key specs explained for this plug
Thread Standard: G1/4"
This is the universal thread size for custom loop fittings. You can use this plug to seal any port that accepts a G1/4 inch connection. It ensures compatibility with most radiators, blocks, and reservoirs on the market. You do not need adapters for standard components.
Construction: CNC machined brass
Brass provides durable threads that resist stripping during installation. The CNC machining ensures precise tolerances for a tight seal. This material choice offers reliability for long-term use in your cooling loop. You get a sturdy fitting that maintains its integrity over time without deformation.
Finish: Satin Titanium
This coating protects the brass from corrosion and matches other titanium-finished components. It gives the fitting a consistent aesthetic for your build. You can mix this with other satin titanium parts for a unified look. The finish helps maintain appearance without frequent cleaning or polishing.
Seal: Quality rubber O-ring
The O-ring creates a leak-proof barrier when the plug is tightened. This prevents coolant from escaping the unused port. You rely on this seal to keep your system dry and safe. The rubber material compresses to fill any minor gaps in the threads for a secure fit.
Diameter: 23mm
This measurement describes the outer width of the plug head. You need this dimension to ensure the plug fits within your case layout. It helps you plan spacing between fittings and other components. The size is compact enough to avoid interference with nearby tubing or hardware.

You get a consistent aesthetic without the need for additional painting or plating. The design is simple and functional, focusing on sealing unused ports effectively.
The fitting has a diameter of 23mm. This size allows it to fit standard G1/4" ports found on most water cooling equipment. The plug seals with a quality rubber O-ring. This ensures a tight barrier against dust and debris. You do not need to worry about particles settling into open ports on your reservoir or block. The mechanical design relies on precise threading rather than complex internal mechanisms. This simplicity reduces potential points of failure.
There are no electronic components or moving parts listed in the specifications. The unit operates purely through mechanical compression. You install it by hand or with a standard fitting wrench. The layout is compact, ensuring it does not interfere with surrounding tubing or components. The build quality suggests it is designed for long-term use in custom loops. The materials listed indicate a focus on durability and visual consistency. You can trust the brass and titanium combination to maintain its integrity over time.
Installation and Daily Use
Setting up this fitting is straightforward. You simply screw the plug into any unused G1/4" port on your loop components. The internal rubber O-ring creates the seal. This design prevents dust and debris from entering the system when a port is not in use. The plug is compatible with standard water cooling equipment. You can use it on radiators, pump/reservoir combos, and water blocks that accept G1/4" threads. The CNC machined brass body ensures a tight fit. The Satin Titanium finish adds a layer of protection against corrosion and wear. This helps maintain the aesthetic of your loop over time. The diameter of 23mm allows for easy handling during installation. You do not need special tools beyond a standard wrench or pliers. Daily use involves leaving the plug in place permanently. It keeps the interior of your cooling system clean. This reduces the risk of contamination in the coolant. The sealed design also prevents minor leaks if the port was previously open. The plug fits securely without requiring excessive torque. This makes it reliable for long-term use. You can trust the brass construction to hold up under pressure. The O-ring remains effective for years. This fitting is ideal for builders who want to keep their loops tidy. It is also useful for those who frequently change components. You can seal off ports that are no longer needed. The simple design means there are no moving parts to fail. It just works as a solid barrier. This ensures your cooling system remains efficient and protected.
Before You Buy This Plug
You need this plug to complement your existing G1/4 inch components. It seals unused ports on radiators, blocks, and reservoirs. Verify your ports match the standard thread size before purchasing. The included rubber O-ring maintains the seal over time. You should inspect the O-ring periodically for wear or damage. Replace it if you notice any cracks or flattening. This fitting works alongside other Quantum series parts. It fits well with your current loop setup. You do not need additional adapters for standard ports. The Satin Titanium finish matches other premium fittings. Keep spare O-rings on hand for future maintenance. This simple component prevents dust from entering your system.
