Fitting EKWB HDC 14 — messing, titanium afwerking, hoogte 15 mm, binnenbuis-Ø 14 mm

EKWB HDC 14 — brass fitting with a titanium-coloured satin finish, 15 mm height and inner tube diameter support of 14 mm. This compression-style hard-tube fitting is designed for use with solid tubing such as acrylic and PETG in PC liquid-cooling loops, providing a compact sealed connection between tubing and components like radiators, water blocks and pumps. The fitting body and compression parts are CNC-machined from brass and use rubber O-rings for sealing; the exterior satin titanium surface is intentionally not painted on the inner bore to reduce potential contaminants in the loop.

Advantages

The fitting delivers a minimalistic appearance with no external branding and offers interchangeable colored aesthetic rings (sold separately) for visual customization. A locking compression ring compresses the rubber gasket to secure solid tubing and prevents pull-out, while external grooves allow easier hand tightening. The fitting’s barb and compression ring feature a high-quality satin finish and are compatible with other EK Water Blocks liquid-cooling components.

Suitable for

• Custom PC liquid-cooling loops using hard tubing (Acrylic, PETG)
• Connections to radiators, CPU/GPU water blocks and pump/reservoir ports
• Compact builds where a low-profile 15 mm fitting height is required

Key specifications

• Material: CNC-machined brass (body and compression parts)
• Finish: Satin titanium-coloured exterior; inner bore left unpainted
• Supported inner tube diameter: 14 mm
• Outer diameter (fitting): 22 mm
• Height: 15 mm
• Seal type: Rubber O-rings
• Compression locking ring with pull-out prevention
• Hand-tightening grooves; barb interior with 9 mm hex socket for installation

How to use

Install the fitting by sliding the compression ring and any chosen aesthetic ring onto the solid tube, then insert the tube onto the fitting barb until it seats against the stop. Screw the compression locking ring down to compress the rubber gasket and secure the tube. For initial tightening of the barb onto mating threads, use a 9 mm Allen key inserted into the socketed interior of the barb to avoid damaging fingertips; do not over-tighten — apply controlled torque to avoid stressing adjacent cooling components. Ensure O-rings are properly seated and check for leaks after filling the loop.

Recommendations

Use soft, even pressure when tightening compression rings and avoid excessive torque with the 9 mm Allen key. Keep the inner bore free of coatings or contaminants and confirm compatibility with other fittings and EKWB components. Colored aesthetic rings are optional accessories sold separately; verify ring installation order (aesthetic ring before compression ring) during assembly.
