Multi-Link Fitting for 12mm Hard Tubing

This four-pack of G1/4" compression fittings is built for custom liquid-cooling loops that use 12mm outer-diameter rigid tubing. The multi-link design lets builders extend runs or bridge components without extra adapters. Machined from high-quality brass, each fitting is engineered for a secure, leak-free seal when assembled correctly. The silver finish matches common loop aesthetics.

Thermal and Acoustic Behaviour in Operation

As passive brass components, the fittings add no active heat, noise or power draw to the system. They simply conduct coolant between blocks, radiators and reservoirs at whatever temperature and flow rate the loop provides. Correct torque during installation ensures zero leakage under normal operating pressure. No electrical connection or control software is involved.

What the Four-Pack Changes for the Builder

Supplying four fittings in one package covers the most common multi-link extension scenarios — such as parallel GPU blocks, distribution plates or reservoir top ports — without separate purchases. The RoHS-compliant brass construction keeps material quality consistent across all connection points. Buyers who need different tube diameters, angled rotary joints or coloured accents will need separate fittings not included here.

Questions about this item

How do I install the Bitspower G1/4" Multi-Link fittings on 12mm OD rigid tubing and what step is most often done incorrectly?

Slide the compression ring and nut onto the tube, insert the tube fully into the fitting body until it seats against the internal stop, then tighten the nut by hand plus a quarter turn with a wrench; the step most often missed is not pushing the tube all the way to the stop before tightening.

What maintenance or replacement will these brass multi-link fittings need over time?

Inspect the internal O-rings annually for hardening or cracking and replace them if any coolant weep appears; the brass bodies and compression rings do not wear out under normal use.

What is the first limit that appears when these fittings are used in a continuously running loop?

The practical limit is the combined length of rigid tubing runs; each additional fitting adds a potential leak path and flow restriction, so long multi-link chains should be pressure-tested thoroughly before final fill.
