Alphacool G1/4 Female Extender Fitting

This Alphacool fitting connects two G1/4 male-thread components in a custom liquid-cooling loop. The Deep Black chromatised brass body resists peeling and maintains its colour over time. A wide inner diameter supports high-flow configurations for efficient coolant movement.

Builders extending rigid or flexible tubing runs

Suits enthusiasts who need extra length between blocks, radiators or reservoirs without adding angled adapters. Not for systems using non-G1/4 thread standards or builders who require rotary or angled fittings for tight clearances.

Single extender fitting included

The package supplies one female-to-female G1/4 bushing ready for immediate installation. No additional seals, tools or tubing are bundled, so buyers must source compatible tubing and coolant separately.

Questions about this item

Which G1/4 male-threaded components must I already have to connect this female-to-female extender?

You need two G1/4 male-threaded parts — such as radiator ports, pump tops, reservoir terminals or angled adapters — so each end of the extender can screw onto a male thread.

Will the Deep Black chromatised finish on this extender match older Alphacool Chrome or Shiny Copper fittings I already own?

The Deep Black finish is a distinct colour; it will not match Chrome or Shiny Copper parts, but the G1/4 threads are identical so they connect mechanically without issue.

How can I confirm the extender is seated correctly and flowing freely after installation?

Pressurise the loop and check that no coolant escapes from either joint; then verify flow rate matches the rest of the circuit — unrestricted passage through the inner diameter means the extender is working as intended.
