Precision Compression Fitting

The Alphacool Eiszapfen 13/19 mm G1/4 fitting is a high-end connector designed for custom liquid-cooling loops using hard tubing. It suits builders who demand a secure, leak-free seal and a consistent matte black aesthetic. The G1/4 thread ensures compatibility with 95% of water-cooling components on the market. This single fitting is sold new for expanding or completing a premium loop.

Coated Brass Construction

A special surface procedure binds the deep matte black coating firmly to the brass body, preventing chipping or peeling during installation or transport. The connecting nut features slanted corners that press the included O-ring tightly against the 13 mm inner diameter, 19 mm outer diameter tubing for enhanced grip. Three coloured O-rings are supplied, including a UV-reactive option for visual customisation under UV light.

High-Flow Low-Restriction Design

The straight internal geometry is engineered for high flow, minimising hydraulic resistance so the pump operates efficiently without added strain. The precise machining and secure O-ring seat maintain a reliable seal under normal system pressure, eliminating drips that could damage hardware. No moving parts or active cooling are involved, so the fitting adds zero noise and negligible thermal load to the loop.

Questions about this item

Does the G1/4 thread on this Alphacool Eiszapfen fitting work with most water-cooling components?

Yes, the G1/4 thread is compatible with 95% of components, so it fits nearly every block, radiator, pump or reservoir that uses the same standard.

What tube dimensions does the 17238 fitting accept?

It is made for hard tube with a 13 mm inner diameter and a 19 mm outer diameter; the compression nut and O-ring seal directly on those dimensions.

How do I install the fitting without leaks?

Slide the compression nut over the tube, press the tube fully onto the barb until it seats against the O-ring, then tighten the nut by hand plus a quarter turn with a wrench — the angled nut corners lock the O-ring in place.
