PrimoChill Dual Male G1/4 Extension Coupler Brass Silver Nickel 10 20mm

G1/4 Extension Coupler for Custom Loops

The PrimoChill Dual Male G1/4 Extension Coupler connects two female G1/4 threaded fittings in a custom liquid-cooling loop. It is machined from brass with a silver nickel finish and diamond knurling for grip. The coupler adds 20 mm overall length with 10 mm of exposed body between threads. It suits builders who need a straight spacer between components.

Replaces Improvised Spacers or Mismatched Fittings

Using this coupler removes the need to stack multiple fittings or use mismatched adapters to bridge a gap. The jump is worth it when a clean, rigid connection with consistent threading is required and the 20 mm overall height fits the available space. It eliminates potential leak paths introduced by chaining separate adapters together.

Suits Builders Needing a Fixed 20 mm Male-to-Male

This coupler fits loops where a precise 20 mm male-to-male extension solves the routing problem. Builders who need adjustable length, angled offsets, or a different thread standard should look at other solutions. It is not for systems using non-G1/4 threads or installations where the fixed height cannot be accommodated.
