## Summary description

EK Water Blocks EK-HD 10/12mm is a brass barb fitting designed for use with 10 mm inner / 12 mm outer diameter cooling tubing. Manufactured from brass for corrosion resistance and mechanical durability, it provides a secure push-fit connection between tubing and liquid-cooling components in PC water-cooling loops, useful for custom loop assembly and maintenance.

## Long description

EK Water Blocks EK-HD 10/12mm is a brass barb fitting engineered for 10 mm inner / 12 mm outer diameter cooling tubing used in PC water-cooling loops. Machined from brass and fitted with quality O-rings, this solid-tube female type adapter provides a secure push-fit connection between soft or solid tubing and liquid-cooling components. The design is compatible with EK-CSQ series angled adapters (45°/90°) and is intended for reliable mechanical durability and corrosion resistance in custom loop assemblies and maintenance tasks.
Advantages
The brass construction offers long-term resistance to corrosion while maintaining mechanical strength under repeated assembly and disassembly. Precision machining ensures tight tolerances for consistent sealing when combined with the supplied O-rings. Its female solid-tube design supports use with acrylic or copper tube while remaining compatible with standard 10/12 mm soft tubing, enabling flexible integration into custom cooling loops. The push-fit connection simplifies installation without requiring additional clamps for typical setups.
Suitable for
 Custom PC water-cooling loop assembly with 10 mm ID / 12 mm OD tubing
 Connecting soft tubing to liquid-cooling components and adapters
 Use with acrylic or copper solid tubing where a female solid-tube adapter is required
 Maintenance and part replacement in desktop liquid-cooling systems
Key specifications
 Material: machined brass
 Tube compatibility: 10 mm inner diameter / 12 mm outer diameter soft tubing; compatible with solid acrylic and copper tubing
 Seal type: quality O-rings for push-fit sealing
 Adapter type: female solid-tube barb fitting
 Compatibility: compatible with EK-CSQ series angled adapters (45° and 90°)
How to use
Ensure tubing or solid tube ends are clean, cut squarely and free of burrs before installation. For soft tubing, push the 10/12 mm tube onto the brass barb until it seats against the adapter body and O-ring; for solid tubing, slide the tube into the female adapter interface as intended for your loop design. When using in combination with EK-CSQ angled adapters, install the adapter components according to their alignment and hand-tighten to avoid cross-threading. Verify all O-rings are present and seated correctly to maintain a leak-free connection.
Usage recommendations
Perform a leak test after assembly by filling the loop and running the pump at low speed for several minutes. Avoid excessive mechanical stress on tubing near the fitting and periodically inspect O-rings for wear; replace O-rings if signs of deterioration appear. Use compatible tubing dimensions (10 mm ID / 12 mm OD) or specified solid tubing to ensure proper fit and sealing.
