G1/4 Brass Extension Coupler

The PrimoChill Dual Male G1/4 Straight Coupler connects two female G1/4 threaded fittings in a custom liquid-cooling loop. Its solid brass body provides durable, corrosion-resistant sealing for DIY builders. The SX Sky Blue finish adds a consistent colour accent across the system.

Builders joining female ports

This coupler suits anyone needing to bridge two female G1/4 components such as radiators, blocks or reservoirs. It does not serve builds that require angled routing, rotary adjustment or a reduction to a smaller thread size.

Compact 10 mm body with 20 mm overall length

The short profile fits tight spaces between components while maintaining full thread engagement. Headroom is limited to straight inline connections; offsets or multi-port distribution need different fittings.

Questions about this item

What thread size must my existing fittings have to connect with this G1/4 coupler?

Your fittings need G1/4 threads; the coupler has dual male G1/4 threads so it joins two female G1/4 ports directly.

Will the 20 mm overall height clear the space between my current water-block and reservoir?

The coupler measures 20 mm with threads and 10 mm without, so measure the gap between components to confirm clearance.

How can I verify the seal is leak-free after installing the brass coupler?

Pressurise the loop slowly and watch each G1/4 joint for drips; a dry brass coupler with no moisture at the threads confirms a good seal.
