Thermaltake CL-W163-OS00BL-A TT Premium Black Coolant Dye

The Thermaltake TT Premium Concentrate Dye in black is a liquid coloring additive designed to transform the appearance of custom liquid cooling loops. Each 50ml bottle is formulated to color up to 1000ml of total coolant when used with Thermaltake's C1000 Opaque White or C1000 Pure Clear coolant lines. The concentrated format allows builders to control the intensity of the color by adjusting the amount of dye added, and multiple TT Premium dye colors can be mixed together for fully custom shades — a feature that opens up a wide palette for themed or color-coordinated PC builds.

Beyond aesthetics, the dye is engineered with practical considerations for long-term use in a cooling loop. Its non-flammable, biodegradable, and virtually odorless formula includes anti-corrosion properties compatible with copper, nickel, brass, and aluminum — the most common materials found in water blocks, radiators, and fittings. With a 2-year shelf life, it can be kept on hand for future maintenance or loop rebuilds. While it adds no thermal performance benefit, the TT Premium Concentrate Dye is a reliable choice for builders who want to personalize their cooling system's look within the Thermaltake coolant ecosystem.
