## Summary description

EKWB HDC 12 fitting is a brass compression fitting with a titanium-coloured finish, designed for liquid cooling loops in PCs. It has a height of 15 mm, outer diameter 20 mm and supports a tube diameter of 12 mm. Suitable for connecting rigid or soft tubing in custom water-cooling setups to ensure leak-resistant joins.

## Long description

EKWB HDC 12 — brass, titanium finish, height 15 mm, diameter 20 mm, tube Ø 12 mm is a compact compression fitting engineered for PC liquid-cooling loops. Made from CNC-machined brass with a satin titanium-coloured finish, this 15 mm tall fitting accepts 12 mm outer-diameter rigid or soft tubing and provides a secure, leak-resistant connection. The product is part of the EK-Quantum Torque HDC 12 line and is designed with a minimalistic appearance, removable aesthetic rings (sold separately) and a rubber gasket that the locking ring compresses to lock tubes in place. The interior is intentionally uncoated to minimise potential contaminants in the cooling loop.
Advantages
The fitting combines durable brass construction with a satin titanium-colour finish for consistent appearance and corrosion resistance. A locking compression ring compresses an internal rubber gasket to prevent tube pull-out while external grooves improve hand-tightening. The compression ring features cutouts that expose an interchangeable aesthetic ring for customizable looks. The barb and compression components are CNC machined for dimensional accuracy and reliable sealing, and the fitting is compatible with other EK Water Blocks liquid cooling products.
Suitable for
 Custom PC liquid-cooling loops using 12 mm outer-diameter tubing (rigid or soft)
 Hard tubing builds with Acrylic or PETG
 Upgrading or matching EK-Quantum series components in a minimalistic aesthetic
 Small or compact builds that require low-profile fittings (15 mm height)
Key specifications
 Material: CNC-machined brass (external satin titanium finish)
 Finish: Satin titanium-coloured exterior; interior left uncoated
 Height: 15 mm
 Outer diameter: 20 mm
 Supported tube outer diameter: 12 mm
 Seal: Rubber O-ring (compression seal under locking ring)
 Compatibility: Designed for use with Acrylic and PETG hard tubing and compatible with EK Water Blocks liquid cooling products
 Installation interface: Barb socketed for 9 mm hex Allen key
How to use
Prepare the 12 mm tubing by cutting square and deburring the end to ensure a smooth fit. Screw the aesthetic ring onto the fitting (if used) before fitting the compression ring, then slide the compression ring into place and insert the tube fully onto the barb until it seats against the internal stop. Tighten the locking/compression ring by hand using the external grooves; if additional torque is required, use a 9 mm Allen key in the barb socket to hold the fitting while turning the compression ring, taking care not to over-tighten. Verify the rubber O-ring properly compresses around the tube to form a leak-resistant seal. Perform a pressure or leak test of the complete loop before full system operation.
Usage recommendations
Use only 12 mm outer-diameter tubing specified for hard- or soft-tube water-cooling. Install the aesthetic ring prior to the compression ring if you plan to use colored rings. Use an Allen key 9 mm to support the barb during installation to protect fingertips and avoid applying excessive force that could damage adjacent components; hand-tightening is normally sufficient. Do not expose the fitting interior to paints or coatings, and follow standard leak-testing procedures before powering the system.
