1/4″ Fill-Port Fitting for Custom Loops

The Thermaltake Pacific CL-W036-CU00BL-A is a G 1/4 threaded fitting designed for DIY liquid-cooling builds. It accepts tubing with a 6.35 mm inner diameter and provides a dedicated fill port for the loop. The black chrome-plated brass body weighs 12 g.

Connects Directly to G 1/4 Ports

The fitting screws into any component with a matching G 1/4 thread such as radiators, reservoirs or pump tops. Its 16 mm diameter and 17.5 mm height keep the profile low inside the case. The stop-to-tube design secures the line without additional clamps.

Brass Construction Resists Corrosion

The copper-based alloy resists coolant degradation during normal operation. A high-flow internal passage minimises restriction so pump speed and noise stay unchanged. The sealed port cap prevents leaks while the system runs.

Questions about this item

What internal diameter tubing does the G 1/4 fill-port fitting accept?

The fitting is designed for tubing with a 1/4 inch (6.35 mm) inner diameter.

How much heat can the brass fitting transfer during continuous loop operation?

The copper-based brass construction conducts heat efficiently, but the fitting itself adds negligible thermal load to the loop.

Which thread standard must the reservoir or block port match for this fitting to seal?

The port must provide a G 1/4 thread to mate with the fitting’s screw thread.
