Alphacool Eiszapfen Quick Release Female

The Alphacool Eiszapfen quick release fitting is built for custom water cooling loops that need fast, tool-free changes. A G1/4 external thread fits standard radiators, reservoirs and pump tops. The female connector pairs with a separate male plug so you only buy the halves your build requires. High-quality brass with a chrome finish resists corrosion inside the loop.

Thermals noise and power

As a passive brass fitting it adds no heat, no noise and draws no power. The N.D.S.L. valve seals both sides instantly when uncoupled, so coolant stays in the loop and components stay dry during maintenance or reconfiguration. Flow restriction is minimal, preserving the pump performance you have already tuned.

Upgrade path and value

This fitting replaces fixed compression joints wherever you want to disconnect tubing without draining the system. The jump is worth it when you frequently swap components, test different blocks or transport a filled loop. Builders who never open their loop after the first fill will not need the quick release function.

Questions about this item

How do I install the Alphacool Eiszapfen Female G1/4 quick release, and what step is often missed?

Thread the 86 x 32 x 32 mm brass body into a G1/4 port on a radiator, reservoir or pump top, then tighten with a wrench on the flats — the step many skip is confirming the O-ring seats fully before pressurising the loop.

What maintenance or replacement will the Alphacool 17439 quick release need over time?

Inspect the internal N.D.S.L. valve seals annually; replace the coupling if any coolant weep appears at the latch, since the brass body itself does not degrade.

What limit appears first when the Alphacool Eiszapfen Female runs under sustained load?

The G1/4 thread depth and 32 mm width restrict how many fittings can sit side-by-side on dense radiator end-tanks, so port crowding becomes the practical bottleneck.
