Barrow Mods G1/4" Extension Fitting

The Barrow Mods TBZT-A10-BK is a female-to-female extender built from high-quality brass with a black finish. It adds 10.5mm of length to a standard G1/4" port so larger fittings can be attached or two fittings can be joined directly. This fitting is designed for custom liquid-cooling loops where components sit close together.

Who this suits and who should look elsewhere

This part suits builders who need to bridge a small gap between a block and a fitting without using tubing. It also helps when a bulky fitting would otherwise interfere with a neighbouring component. Buyers who need a different thread standard, a longer offset, or an angled connection will not be served by this fixed 10.5mm straight extender.

Critical specification

The extender provides exactly 10.5mm of additional thread engagement on a G1/4" interface. Verify that your blocks and fittings share this thread and that the 10.5mm extension clears the obstruction without exceeding the available space.

Questions about this item

Will the G1/4 threads on this extender fit my existing Barrow fittings?

Yes, both ends use standard G1/4 threads so they connect directly to any G1/4 male fitting or component.

How do I install the extender without stripping the brass threads?

Hand-tighten each side until the O-ring seats, then give a very slight turn with a soft-jaw wrench; over-tightening brass damages the threads.

Do the O-rings on this 10.5 mm extender need periodic replacement?

The internal O-rings can degrade after several thermal cycles; inspect them during loop maintenance and replace if they show flattening or cracking.
