Brass G1/4 Straight Coupler

The PrimoChill dual male straight coupler joins two female G1/4 ports in a custom liquid-cooling loop. Its brass body and diamond-knurled ends provide secure hand-tightening without tools. The SX Satin Black finish matches other PrimoChill components for a uniform appearance. This fitting suits builders who need a short, rigid bridge between components.

20 mm Installed Height

The coupler measures 20 mm overall with threads engaged and 10 mm of exposed barrel once seated. This fixed length determines the gap between the two connected fittings and cannot be adjusted. Builders requiring a different spacing must choose an alternative coupler length or a rotary adapter. The G1/4 thread pitch is the only compatibility factor.

Brass Construction Under Pressure

Brass resists deformation and corrosion during continuous coolant circulation and normal operating temperatures. The material maintains seal integrity without the stress relaxation seen in softer metals over long periods. Diamond knurling preserves grip for future disassembly after extended thermal cycling. The coupler is not designed for flexible or offset connections.

Questions about this item

What does the 20 mm overall height mean once the coupler is installed?

The 20 mm measurement includes both G1/4 threads, so the coupler adds that much length between the two female fittings you connect to it.

What does the G1/4 thread standard limit in a custom loop?

G1/4 is the common water-cooling thread size; it determines which fittings, blocks, radiators and reservoirs can screw directly into this coupler.

What clearance is needed to fit the 20 mm long coupler?

You need at least 20 mm of straight space between the two female ports you are joining, plus room for a spanner on the diamond-knurled body.
