PrimoChill G 1/4in SX Knurled Nickel Slotted Stop Fitting diy cooling

G 1/4in Threaded Stop Fitting

This PrimoChill G 1/4in SX knurled stop fitting caps unused ports in a custom water-cooling loop. It is made from coated brass with a powder-coated finish for colour matching across the SX collection. The male G 1/4in thread fits standard water-block, radiator or reservoir ports. A sealing O-ring is included to ensure a leak-free closure.

Knurled Brass With O-ring Seal

The knurled body allows hand-tight installation without tools, while the slotted head accepts a screwdriver if extra torque is needed. Over-tightening is unnecessary and can make removal difficult, so finger pressure is sufficient. The coated brass construction resists corrosion inside the loop. This fitting frees up no additional space but provides a clean termination point for any open G 1/4in port in the build.

SX Collection Colour Match

The powder-coated Candy SX finish is designed to match other PrimoChill SX fittings so the entire loop shares a consistent tone. Knurled surfaces appear darker than smooth ones, a variation noted by the manufacturer. The single stop fitting and its O-ring are the only items supplied; no extra adapters or tools are bundled. The 20-year-old US brand backs the component with domestic support and craftsmanship.
