G1/4" Multi-Link Fitting for 12mm OD Rigid Tubing

This four-pack of Bitspower compression fittings connects 12mm outer-diameter hard tubing in a custom liquid-cooling loop. Each fitting uses a standard G1/4" thread and a multi-link design that allows direct tube-to-tube extension runs. The brass construction and white finish suit builders who want a clean, uniform look across multiple connection points.

G1/4" Thread Compatibility and Hard-Tube Constraints

The G1/4" thread is the de facto standard for water-cooling components, so these fittings screw into most blocks, radiators, reservoirs and pumps. They only accept rigid tubing with a 12mm outer diameter; softer or differently sized tube will not seal. The multi-link layout is intended for straight extension segments, not for sharp bends or angled routing.

Simple Compression Installation with Common Pitfalls

Installation requires chamfering and deburring each tube end, then sliding the compression nut and collet onto the tube before tightening the body by hand plus a light wrench turn. The most frequent issue is an uneven cut that lets the O-ring bypass, causing a slow leak. Over-tightening can crush the collet or strip the brass threads, while forgetting to fully seat the tube leaves a gap that pressurised coolant will exploit.

Questions about this item

Should I choose the 4-pack or look for a different quantity?

This listing is a 4-pack of G1/4" multi-link fittings for 12mm OD hard tubing, so choose it if you need four identical connections in a single purchase.

What does the 12mm OD specification mean when I install these in my loop?

It means each fitting accepts rigid tubing with a 12mm outer diameter, giving a secure compression seal when assembled correctly.

What does the G1/4" thread limit in my build?

The G1/4" thread fits standard water-block, radiator and reservoir ports, so it caps compatibility to components that use that same thread size.
