Concentrated UV‑red coolant for custom loops

Mayhems XT‑1 Nuke Coolant Concentrate is a 250 ml bottle of ethylene‑glycol based fluid designed for PC water‑cooling systems. It ships as a concentrate so you can set the exact dilution ratio with distilled water. The UV‑reactive red dye glows under black‑light for visual effect.

Dilution flexibility and material compatibility

You decide the final mix, adjusting boiling and freezing points to suit the loop. The formula includes non‑toxic corrosion and scale inhibitors that protect copper, brass, steel, nickel and aluminium components. It is also PETG safe and contains resilient biocides for long‑term biological control.

Extreme temperature headroom

The concentrate is rated for pressurised operation from –50 °C up to 390 °C, giving wide margin beyond typical PC loads. A single 250 ml bottle yields up to 50 litres of ready‑to‑use coolant when diluted, covering large or multiple loops. It is not suited for builders who need a pre‑mixed, pour‑and‑go fluid.

Questions about this item

Should I buy the 250 ml concentrate or look for a larger volume?

The 250 ml bottle is the only size listed. Dilute it with distilled water at your chosen ratio to reach the total loop capacity you need.

What temperature range does this coolant actually handle once it is inside my loop?

The concentrate is rated for pressurised environments up to 390 °C and down to –50 °C, giving a very wide operating window.

Does the proprietary glycol blend require any special fittings or tubing standards?

No special interface is needed; it works with standard water-cooling components and protects copper, brass, steel, nickel and aluminium.
