Alphacool Eiszapfen 16mm G1/4 HardTube Knurled Compression Fitting Chrome 17265

Precision HardTube Fitting

The Alphacool Eiszapfen 17265 is a G1/4 compression fitting engineered for 16mm rigid tubing in custom liquid-cooling loops. Its knurled nut design provides secure finger-tight assembly without tools. The chrome-plated brass construction resists corrosion while delivering a premium metallic finish. This component targets builders who demand exacting fitment and visual consistency in high-end open-loop systems.

High-Flow Thermal Path

Internal geometry is optimised for unrestricted coolant passage, minimising pressure drop across the joint. The slanted nut corners compress the O-ring evenly against the tube wall, creating a reliable seal that withstands vibration and thermal cycling. No moving parts or restrictive adapters are present, so pump workload and loop acoustics remain unaffected. The durable coating process prevents surface degradation that could introduce particulates into the fluid over time.

Colour-Coded Seal Kit

Each fitting ships with three interchangeable O-rings in distinct colours, allowing immediate visual identification of flow paths or aesthetic matching. The supplied UV-reactive option fluoresces under ultraviolet lighting for enhanced loop visibility. This bundled variety eliminates the need to purchase separate seal packs for colour coordination or leak-testing contrast. The knurled nut remains captive during O-ring swaps, simplifying maintenance without risk of lost hardware.
