Bitspower G1/4" Male-Female Extender Fitting

This Bitspower BP-MBWP-C65 extender connects G1/4" threaded components in a custom liquid-cooling loop. Its 40 mm length adds spacing between blocks, radiators or reservoirs while maintaining a clean matte-black finish. The brass construction and hidden O-ring design provide a reliable seal for DIY builders.

Suits builders needing extra reach between G1/4"

The fitting works for loops that require a short male-to-female extension in a single orientation. It does not serve builds that need a female-to-female coupler, an angled adapter or a rotary fitting for alignment flexibility. Buyers who want a different thread standard or a longer extension should look at other parts.

40 mm male-to-female extension length

This single dimension determines whether the extender bridges the gap in your specific loop layout. Verify the required spacing before purchase, as the fixed 40 mm size cannot be adjusted or shortened once installed.

Questions about this item

How do I install the G1/4" male-female extender without cross-threading the brass threads?

Hand-tighten the male G1/4" end into the component first, then thread the female side onto the tubing fitting; finish with a quarter-turn using a soft-jaw wrench to seat the hidden O-ring without damaging the matte black finish.

Will the hidden O-ring need replacement, and how can I tell?

The hidden O-ring is designed for long-term sealing; inspect it for flattening or cracking during loop maintenance — if coolant weeps at the joint, replace the O-ring with a standard G1/4" size.

At what length does the 40 mm extender start to restrict flow in a high-flow loop?

The 40 mm true hi-flow bore adds negligible restriction; the first limit under sustained use is typically the pump head pressure, not the extender length.
