Fittingsæt Alphacool 17376

Eiszapfen 13mm HardTube compression fitting G1/4 - knurled - chrome sixpack. The Alphacool Eiszapfen Connector Series is a high-end range of compression fittings designed for custom water-cooling systems. These fittings combine high flow, precise machining and durable surface finishes. Available in brilliant chrome or matte black, the fittings feature a bonded outer coating that resists chipping and peeling and an Alphacool logo for easy identification. The slanted nut edges ensure the O-ring sits tightly against 13 mm HardTube for a secure seal, and the kit includes three O-ring colours with an optional UV-reactive variant.

Advantages

The compression fitting provides a secure G1/4 connection and is machined for reliable high-flow performance. A special coating process bonds the surface finish to the metal to increase longevity and reduce wear. The nut geometry improves O-ring seating for better transport and handling safety. Included colour O-rings and optional UV-reactive parts offer visual customization while maintaining compatibility with standard HardTubes.

Suitable for

• Custom PC water-cooling loops using 13 mm (outer diameter) HardTube
• High-flow radiator and block connections requiring G1/4 threads
• Systems where durable, corrosion-resistant chrome fittings are preferred

Key specifications

• Model: HardTube Compression Fitting 13mm
• Thread: G1/4 (1/4") outer thread
• Compatible tube OD: 13 mm HardTube
• Finish: Chrome (also available in matte black)
• Pack: sixpack (set of six fittings)

How to use

Slide the included O-ring over the 13 mm HardTube end, insert the tube into the compression fitting until it seats against the internal stop, then screw the knurled nut onto the G1/4 thread and tighten by hand or with a suitable tool until the O-ring is compressed and forms a leak-free seal. Ensure the tube is cut square and free of burrs before assembly. Do not overtighten; tighten enough to compress the O-ring securely.

Recommendations

Use with compatible 13 mm outer-diameter HardTube only. Verify thread compatibility (G1/4) with other components. Inspect O-rings before installation and replace if damaged. For best longevity, avoid aggressive chemicals and extreme abrasive cleaning on the chrome finish.
