Dual Female G1/4 Coupler for Custom Loops

This straight coupler joins two male G1/4 fittings in a custom liquid-cooling loop. It provides a direct, inline connection without changing tube direction or adding angled bends. The nickel-silver finish matches other PrimoChill components for a consistent aesthetic.

Hand-Tight Installation with Knurled Grip

Diamond-pattern knurling on the 18.5 mm outer diameter gives a secure finger grip for tool-free tightening. Over-tightening with pliers can damage the powder-coated brass threads or crack acrylic blocks. Ensure both male fittings have clean, undamaged threads before assembly to prevent leaks.

Fixed Length Limits Loop Layout Options

The 16 mm overall height sets a rigid spacing between the two connected components. Builds that require variable spacing or a shorter gap cannot use this coupler. It only bridges male-to-male G1/4 threads; female-to-female or mixed-thread connections need different adapters.

Questions about this item

How do I verify the coupler is seated correctly after threading it onto my G1/4 fittings?

Check that both female G1/4 threads engage fully and the 16 mm by 18.5 mm body sits flush without gaps, then pressure-test the loop for leaks before powering on.

What comes in the package and do I need extra seals or tools?

The box contains one Dual Female G1/4 Straight Coupler; no additional O-rings or tools are included, so reuse the seals already on your male fittings.

Which version of this coupler should I pick for a standard G1/4 loop?

This single model fits any G1/4 threaded male fitting, so choose it when you need a straight female-to-female connection in 16 mm by 18.5 mm nickel-plated brass.
