Rose Gold G1/4 PETG Fittings

The Thermaltake Pacific C-Pro series delivers six compression fittings finished in rose gold for custom liquid-cooling loops. Each fitting accepts 16mm outer-diameter PETG tubing and threads into standard G1/4 ports on blocks, radiators and reservoirs. The pack suits builders assembling a single-loop system with a coordinated colour theme.

G1/4 Thread and 16mm Tubing Limits

The G1/4 thread pitch is the de facto standard for PC water-cooling components, so compatibility is broad but not universal. Only 16mm OD PETG tubing is supported; smaller or larger diameters, acrylic tubing or soft tubing will not seal correctly. The four pre-installed O-rings are sized for this specific combination and cannot be swapped for other tube dimensions.

Upgrade from Standard Compression Fittings

The C-Pro design replaces conventional two-O-ring compression fittings with a four-O-ring arrangement that simplifies installation and reduces leak risk. The jump is worth it when assembling a new loop or refreshing an older build where fitting reliability is a priority. Builders using mixed tubing sizes or non-G1/4 components will need different fittings.

Questions about this item

Should I buy these 16 mm OD PETG fittings or look for a different tube size?

Choose these fittings only if your loop uses 16 mm outer-diameter PETG tubing; the G1/4 threads fit standard water-blocks, radiators and reservoirs.

What does the high-flow claim mean once the fittings are installed in my loop?

The internal bore is shaped to minimise restriction so coolant moves freely through each fitting, helping maintain pump head pressure across the whole circuit.

Are the G1/4 threads compatible with every water-cooling component I own?

Yes, G1/4 is the near-universal thread for PC liquid cooling, so these fittings screw into virtually any modern block, radiator, pump or reservoir port.
