PrimoChill G1/4 Dual Male Coupler

The PrimoChill Dual Male G1/4 Straight Coupler connects two female-threaded fittings in a custom liquid-cooling loop. Its brass body carries an SX UV Green finish that reacts under UV light. The coupler adds 20 mm of overall height including threads, or 10 mm without threads. It suits builders who need a rigid, colour-matched link between components.

Check thread compatibility and clearance

Verify that every component you plan to join uses standard G1/4 threads before ordering. Measure the available space between the two female ports; the coupler occupies 20 mm with threads engaged. Ensure no adjacent tubing, reservoirs or motherboard heatsinks will interfere with the straight profile. The brass construction requires no special tools beyond a standard fitting wrench.

Replaces improvised adapters or mismatched fittings

This coupler replaces makeshift connections such as short tubing runs with two compression fittings when a solid bridge is cleaner. The jump is worth it when you want a fixed, leak-resistant joint that maintains the loop's UV Green aesthetic. It is not for builders who need angled routing, quick-disconnect functionality or a different thread standard.

How do I choose between the available versions of this coupler?

This model is offered in a single SX UV Green finish with G1/4 threads. There are no other capacity or colour options to select.

What does the 20 mm height mean once the coupler is installed in my loop?
