Fitting extender for tight loops

The Barrow Mods G1/4" male-to-female extender adds 15 mm of length to a water-cooling port. It is machined from nickel-plated brass and finished in black. The part lets builders connect two fittings directly without tubing when blocks sit very close together.

Integrates with standard G1/4" threads

The extender screws into any component or radiator port that uses the common G1/4" thread. It accepts a second G1/4" fitting on its female end, creating a rigid bridge between adjacent blocks. This removes the need for a short tube run and frees up space in crowded loops.

Suits builders with tightly spaced blocks

Ideal for custom loops where GPU and CPU blocks, or multiple radiators, leave almost no gap for tubing. Not suited for builds that require flexible routing, angled connections or a different thread standard. Buyers needing a longer offset or a rotating joint should look at other fitting types.

Questions about this item

How far does the 15 mm extender protrude from a G1/4" port?

The nickel-plated brass body adds exactly 15 mm of clearance between the block port and the attached fitting.

Does the all-metal construction transfer noticeable heat into the loop?

The brass fitting runs at coolant temperature and adds no active heat; it simply conducts what the liquid already carries.

Which thread standard must the existing block and fitting share for this extender to work?

Both the block port and the mating fitting need standard G1/4" threads to connect correctly.
