  • G1/4" thread fits standard water-cooling components
  • 16mm OD rigid tubing compatibility ensures secure seal
  • Six-pack provides enough fittings for a full loop

Premium G1/4" Hex Multi-Link fittings

These compression fittings join 16mm OD rigid tubing in a custom liquid-cooling loop. The matte-black finish suits builders who want a clean, dark aesthetic. The six-pack quantity covers a typical CPU-and-GPU loop with a few spare connections. They are not for anyone using soft tubing or a different outer diameter.

Brass construction and compression seal

Machined from brass, each fitting uses a hex body that accepts a standard wrench for secure tightening. The G1/4" thread mates with most water blocks, radiators, reservoirs and pumps. No thermal, acoustic or power figures apply because the parts are passive. They are not for loops that require angled or rotary adapters.

Six-piece set simplifies ordering

The pack delivers exactly six identical fittings, reducing the chance of mismatched components during assembly. No extra O-rings, tools or coolant are included in the box. They are not for builders who need mixed thread sizes or quick-disconnect couplings.

Questions about this item

How do I install the 16mm rigid tubing into these G1/4" hex multi-link fittings without leaks?

Slide the compression ring and collar onto the tube, push the tube fully into the fitting until it seats against the internal stop, then tighten the hex collar by hand plus a quarter turn with a wrench; the step most people skip is verifying the tube is fully bottomed out before final tightening.

Will the brass fittings or O-rings need periodic replacement in a custom loop?

The brass bodies are durable for the loop's lifetime, but the internal EPDM O-rings can degrade after several years of coolant exposure; inspect them during annual fluid changes and replace if they show cracking or flattening.

At what point does flow restriction become noticeable when chaining multiple 16mm multi-link fittings?

Each fitting adds minimal restriction equivalent to a short straight tube section; measurable pressure drop typically appears only when exceeding six to eight fittings in a single flow path with a standard D5 pump.
