Water-Cooling Fittings for 16mm Tubing

These G1/4-inch copper compression fittings connect 16mm outer-diameter rigid tubing in a custom liquid-cooling loop. The pack contains four silver-coloured pieces made from brass for corrosion resistance. Each fitting uses a compression design that seals without tools and is rated to sustain a drag force of 15kg. They suit builders assembling a high-flow, leak-free hard-line system.

Who Should Use These

The fittings are intended for enthusiasts building a custom water-cooling loop with 16mm hard tubing and G1/4 threaded components. They are not suited for systems using soft tubing, smaller or larger tube diameters, or non-G1/4 thread standards. Buyers needing angled, rotary or quick-disconnect styles will require different fittings.

Deciding Specification

The critical specification is the 16mm outer-diameter tubing compatibility combined with the G1/4 thread size. If the loop uses any other tube diameter or thread pitch these fittings will not fit and cannot be adapted.

Questions about this item

Will the G1/4" threads on these fittings match the standard ports on my existing water blocks and radiators?

Yes, the G1/4" thread is the industry standard for PC water-cooling components, so they will screw directly into the ports on your current blocks, radiators and reservoirs.

How can I verify the compression seal is holding after I assemble the loop with 16mm hard tubing?

Pressurise the loop with a leak tester and watch the pressure gauge; a steady reading with no drips at the four silver fittings confirms the high-flow, leak-free structure is working.

The pack lists four fittings — are any extra O-rings, tubing inserts or tools included?

The box contains only the four G1/4" compression fittings; spare O-rings, tubing chamfer tools or cutting tools for the 16mm rigid tubing must be purchased separately.
