Alphacool Eiszapfen 16 mm HardTube Fitting

This six-pack of chrome compression fittings connects 16 mm outer-diameter rigid tubing to any component with a G1/4" thread. The brass bodies receive a bonded chrome coating that resists chipping and peeling over time. Angled nut corners press the included O-rings firmly against the tube wall for a secure seal. Supplied O-rings come in three colours, with an optional UV-reactive variant available.

Replaces standard compression fittings

The bonded finish and reinforced nut geometry add durability for systems that are moved frequently or shown at events. Builders who have experienced coating wear or loose seals on earlier fittings gain a more reliable connection without changing tube size. The upgrade is worthwhile when appearance longevity and transport safety matter more than basic function alone.

Fits G1/4" ports in custom loops

Each fitting threads directly into radiators, blocks, reservoirs or pumps that accept G1/4" threads, requiring no adapters. The 16 mm hard-tube seat determines the tubing you must purchase; no other tube diameter is compatible. Using these fittings frees you from flexible-tube routing constraints while delivering a clean, rigid aesthetic.

Questions about this item

What outer-diameter hard tube fits the 16mm compression side of these fittings?

The compression end accepts rigid tubing with a 16mm outer diameter, matching the 16mm OD size stated for the Eiszapfen hard-tube socket.

How do I install the G1/4" threaded end, and which step is often missed?

Screw the G1/4" thread into the component by hand, then tighten gently with a wrench on the hex flats; the step many miss is seating the included O-ring on the thread before tightening.

When should I replace the coloured O-rings supplied with the 6-pack?

Replace the O-rings if they become brittle, cracked or lose elasticity, or whenever you disassemble the loop and the rings show any deformation.
