Rose Gold 16 mm OD Compression Fittings
These G1/4 PETG compression fittings use a 16 mm outer-diameter design and a rose gold finish for custom liquid-cooling loops. Four pre-installed O-rings create a high-flow, leak-free seal that simplifies tube installation. The C-Pro series is exclusive to Thermaltake and carries Tt LCS certification. Builders assembling a hard-tube loop with matching PETG tubing will find the fitment straightforward.
Sustained Loop Integrity
Under continuous circulation the four O-ring arrangement maintains a consistent seal without the gradual weep that can appear on traditional two-ring compression fittings. High-flow geometry keeps restriction low so pump head pressure is preserved over long runs. The all-metal construction resists deformation from repeated thermal cycling. Installers who need reliable sealing through months of 24/7 operation gain confidence from the C-Pro design.
Upgrading From Standard Compression Fittings
The C-Pro series replaces older two-ring compression fittings when a tighter seal and easier tube insertion are priorities. The jump is worth it for loops that have shown minor seepage after transport or temperature swings. Builders who prefer push-in quick-connect fittings will not gain the same mechanical grip on 16 mm PETG. The rose gold colour also matches other Pacific components for a uniform aesthetic.

Questions about this item
Does the G1/4 PETG tube fitting generate any noise or heat during continuous liquid-cooling operation?
The compression fitting itself has no moving parts and adds no measurable noise or heat to the loop; only the pump and radiator fans contribute audible or thermal output.
What tubing and thread standard must I already own for these CL-W266-CU00RG-A fittings to work?
You need 16 mm OD PETG hard tubing and components with G1/4 threads; the four pre-installed O-rings seal directly against that tube size and thread pitch.
Will these rose-gold C-Pro fittings mate with older nickel-plated or brass G1/4 blocks and radiators I want to keep?
Yes — the G1/4 thread is the same industry standard, so they screw into legacy blocks and radiators without adapters; the rose-gold finish is purely cosmetic and does not affect the seal.
