Thermaltake Pacific CL-W097-CA00BL-A 16mm PETG Tube Fitting

The Thermaltake Pacific CL-W097-CA00BL-A is a compression fitting engineered for custom PC water cooling loops that use 16mm outer diameter PETG hard-line tubing. Built from copper with a matte black finish, the fitting threads into any G 1/4" port found on water blocks, radiators, reservoirs, and pump tops. Three factory-installed O-rings grip the rigid tube securely, creating a high-flow, leak-free connection without the need for additional sealants or thread tape.

For builders planning a hard-line loop, these fittings serve as the critical link between each component. The standard G 1/4" thread makes them interchangeable with most mainstream water cooling hardware, and the neutral black colorway keeps the focus on the tubing runs and coolant color. Because each fitting is sold individually, builders can purchase exactly the quantity their loop layout demands—typically between eight and twelve for a standard CPU-and-GPU loop.
