Extension coupler for tight clearances

This PrimoChill male-to-female G 1/4in extension coupler adds 50 millimetres of reach so a fitting can clear obstacles in a custom loop. It suits builders who need a little extra length without adding another angled adapter. The coated brass body resists corrosion in mixed-metal systems. Buyers who need a shorter or longer spacer cannot use this fixed-length part.

Thermals noise and power in normal use

The passive brass coupler adds no heat, noise or electrical draw to the loop. Fluid simply passes through the 55 millimetre overall length, so pump performance and coolant temperatures stay unchanged. No fan curves or power phases are involved because the part contains no active components. Installers who want active cooling or temperature sensors must look elsewhere.

Bundled o-ring and finish notes

One installed o-ring on the male thread seals the joint without separate PTFE tape. The Candy SX coating tone varies between knurled and smooth surfaces, so matching adjacent fittings may show a shade difference. No tools, clamps or software are included in the package. Users who prefer a different sealing method or a uniform colour across all fittings will need additional parts.

Questions about this item

How do I install the 50mm SX extension coupler without cross-threading the G 1/4in threads?

Hand-tighten the male end into the component first, then thread the female side onto your fitting; the pre-installed O-ring on the male thread seals without tools, so stop when resistance firms up.

Will the coated brass coupler need the O-ring replaced or the finish refreshed over time?

The installed O-ring on the male side is the only wear item; coated brass resists corrosion, so no refinishing is required unless physical damage occurs.

At 55mm overall height, when does clearance become the limiting factor in a tight loop?

The 55mm stack height (including threads) is the first constraint — measure between components before ordering to ensure the coupler fits without forcing adjacent fittings.
