Deep Black extension fitting for custom loops

The Alphacool G1/4" HF 10mm male-to-male extension fitting in Deep Black connects two female-threaded components in a liquid-cooling loop. It suits builders who want a clean, high-flow link between blocks, radiators or manifolds. The deep black finish resists peeling thanks to a chromatised surface bonded to the brass body.

G1/4" threads with 10 mm inner bore

This fitting uses standard G1/4" outer threads on both ends and provides a 10 mm inner diameter for unrestricted coolant flow. It is the single specification that determines whether the part matches your existing hardware. Verify that every connected component has a G1/4" inner thread before purchase.

Passive component with no thermal or acoustic impact

As a solid brass connector the fitting adds no active heat, noise or power draw to the system. It simply extends the fluid path without affecting pump load or loop temperature. Builders who need active cooling performance should look at radiators, pumps or fans instead.

Questions about this item

How much flow restriction does the 10 mm inner diameter add in a custom loop?

The 10 mm bore is marketed as high-flow, so it adds minimal restriction compared with narrower fittings.

What thread standard do the two G1/4" ends use?

Both ends are standard G1/4 BSPP threads, compatible with any G1/4 female port on blocks, radiators or reservoirs.

How much clearance is needed to fit the male-to-male extension between two components?

The fitting is a straight double nipple; allow enough space for the body length plus thread engagement on both sides.
