Thermaltake Pacific C-PRO G1/4 16mm PETG Tube Fitting - Red

The Thermaltake Pacific C-PRO G1/4 16mm PETG Tube Compression Fitting in red represents a thoughtful evolution in liquid-cooling fitting design. Where traditional compression fittings rely on a single O-ring to create a seal between tube and fitting, the C-PRO employs four pre-installed O-rings in a redesigned housing. This multi-seal approach distributes clamping force more evenly around the tube, reducing the likelihood of leaks and eliminating much of the guesswork involved in knowing when a fitting is tight enough.

Installation is streamlined by the fitting's contoured smaller end, which serves as a built-in grip surface for hand-tightening. This means you can secure connections quickly during a build without reaching for tools, and repositioning fittings during loop planning is far less tedious. The fitting's red anodized finish is consistent and vibrant, pairing well with color-themed builds. It threads into any standard G1/4 port found on radiators, pump-reservoir combos, and waterblocks, making it broadly compatible across brands within the custom liquid-cooling ecosystem.
