Threaded rotary coupler for custom loops

The PrimoChill Dual Male G 1/4in SX Rotary Extension Coupler connects two female G 1/4in ports in a water-cooling circuit. It suits builders who need a compact, rotatable link between rigid or flexible tubing runs. The coated brass body resists corrosion while the rotary joint lets you align fittings without stressing the loop.

Dual male G 1/4in threads with 16.5 mm width

The coupler presents two male G 1/4in threads and measures 16.5 mm across the flats. Overall height with threads is 24.5 mm, dropping to 14.5 mm without them. Two O-rings come pre-installed to seal each connection. Buyers whose blocks or radiators use a different thread standard cannot use this part.

Brass construction handles typical loop temperatures

Coated brass conducts heat away from the joint and withstands normal coolant temperatures without degrading. The rotary seal adds no audible noise because it has no moving parts under flow. Power draw is zero, as the coupler is a passive mechanical component. Users should check rotary joints after case moves to ensure seals remain engaged.

Questions about this item

How much extra length does the 16.5 mm wide coupler add to my loop?

It adds 14.5 mm of body length and 24.5 mm overall including the G 1/4 in. threads.

What does the G 1/4 in. thread standard limit in my build?

The dual male G 1/4 in. threads only mate with female G 1/4 in. ports, so every connected component must use that same thread.

Will the 18 mm width clear tight spaces between my GPU block and radiator?

The coupler measures 18 mm wide, so measure the gap in your loop; it needs at least that much clearance to install without interference.
