Custom Loop Connector

The PrimoChill Dual Male G 1/4in SX Extension Coupler joins two female-threaded fittings in a custom liquid-cooling loop. It provides a straight, rigid link between components such as blocks, radiators, or reservoirs. The coupler suits builders who need to bridge a fixed gap without flexible tubing.

Coated Brass Construction

The body is made from coated brass with a 10mm exposed length and a 20mm overall height including threads. Dual male G 1/4in threads screw directly into standard female ports, while two installed O-rings seal each connection. The knurled finish may appear darker than smooth surfaces under the same lighting.

Ready To Install

One coupler and two pre-fitted O-rings are included so the joint can be assembled immediately. No additional seals or tools are required beyond standard fitting tightening practice. The manufacturer notes that the component is used at the builder's own risk and accepts no liability for hardware damage.

商品問答

How does the G 1/4in thread standard limit what fittings I can connect?

The coupler accepts only components with matching G 1/4in threads, so every block, radiator or reservoir port must use that same thread pitch.

What clearance does the 20mm installed height require in my loop?

You need at least 20mm of straight space between the two female ports you are joining, measured from the face of each port.

How do I install the coupler without damaging the two installed O-rings?

Hand-tighten each male end into its female port until the O-ring seats, then give a light quarter-turn with a wrench; over-torquing crushes the rings.
