G1/4" Male-Female Extender for Custom Loops

The Bitspower BP-MBWP-C64 is a 40mm brass fitting that connects two G1/4" threads in a custom water-cooling loop. It suits builders who need a short, rigid spacer between a component and a rotary fitting or between two rigid tubes. The matte black finish matches dark-themed builds without adding visual clutter.

Brass Construction with Hidden O-ring

Machined from high-quality brass, the extender uses a true hi-flow internal bore to minimise restriction. A hidden O-ring design seats the seal inside the female thread, giving a clean exterior line and reducing the chance of the O-ring snagging during assembly. The matte black coating resists fingerprints and minor abrasion during routine maintenance.

40mm Fixed Length Spacer

This fitting provides exactly 40mm of separation between male and female G1/4" ports. It cannot be shortened or angled, so it only fits layouts where that precise rigid gap is required. Builders needing variable offset, rotation or a longer reach must choose a different fitting type.

Questions about this item

Does the G1/4" thread on this extender restrict flow compared to the tubing?

The true Hi-Flow design keeps the internal bore wide so the G1/4" thread does not become a bottleneck.

What clearance is needed to fit the 40 mm extender in a tight loop?

The fitting adds 40 mm of length and uses standard G1/4" threads, so allow that extra depth plus room for a spanner on the hex.

How is the extender sealed during installation and what is the common mistake?

The hidden O-ring seats inside the female port; the mistake is over-tightening and pinching the ring instead of snugging by hand plus a quarter turn.
