Pacific C-Pro G1/4 Compression Fitting

The Thermaltake Pacific C-Pro Series fitting connects 16 mm OD PETG tubing to a G1/4 thread in a custom liquid-cooling loop. It is built for DIY builders who want a secure seal without the hassle of traditional two-ring designs.

Four Preinstalled O-Rings

Four rubber O-rings come factory-fitted, replacing the usual pair and creating a tighter seal that resists leaks even in cramped routing. The high-flow internal profile keeps coolant moving freely while the copper-and-aluminium body handles 16 mm tubing reliably.

Tool-Free Hand-Tight Install

The knurled collar lets you compress the fitting by hand, so no special wrenches are needed and the 26 mm diameter by 21 mm height body fits tight bends. Over-tightening can damage the O-rings, so stop when resistance firms up. Builders needing angled or rotary joints must buy separate adapters.

Questions about this item

Do the four preinstalled O-rings on the Pacific C-Pro compression fitting need periodic replacement?

The fitting uses four rubber O-rings for its seal; inspect them when draining the loop and replace any that show cracking or flattening to maintain a leak-free joint.

What is the maximum outer-diameter tubing the CL-W211-CU00WT-A can accept without leaks?

This fitting is specified for 16 mm OD PETG tubing; using larger tubing will prevent the compression ring from sealing correctly.

How much heat does the copper-and-aluminium body add to the coolant during all-day operation?

The CU + AL body acts as a passive conductor; it adds no active heat, so coolant temperature rise depends only on your loop's radiator capacity and pump heat.
