G1/4" Male-Female Extender for Custom Loops

This Alphacool Eiszapfen fitting extends a G1/4" thread by 20 mm to bridge gaps between components in a custom water-cooling loop. The black finish resists chipping and matches other parts in the series. It is aimed at builders who need a little extra reach when routing rigid or flexible tubing.

Thread depth limits how far the extender can bridge

The 20 mm length adds a fixed offset; it cannot be shortened or lengthened once installed. If the recessed port is deeper than the extender provides, the connection will still not seat fully. Builders with very deep or unusually spaced ports may need a different length that this part does not supply.

20 mm fixed extension length decides fit

This single measurement determines whether the adapter solves the clearance problem or leaves the thread too short. Check the exact recess depth of your block, radiator or reservoir before ordering; no other dimension in the specification compensates for a mismatch.

Questions about this item

Should I pick the 20 mm extender or a shorter one?

Choose the 20 mm extender when the G1/4" port sits far back or is hard to reach; the extra length clears obstructions without adding another fitting.

How much does the 20 mm length change the loop layout?

It adds 20 mm of straight reach to a G1/4" thread, moving the connection point outward so tubing can route cleanly around tight corners.

Does the G1/4" thread limit flow or pressure in a high-flow loop?

The G1/4" male-to-female thread is the standard water-cooling interface and does not restrict flow in typical custom loops.
