Concentrated UV Green coolant for custom loops

Mayhems XT-1 Nuke is a 250 ml concentrate that you dilute with distilled water to create a UV-reactive green coolant. The proprietary glycol blend includes DeTox™ and PETG-safe additives, non-toxic corrosion inhibitors and resilient biocides designed for long operational life and thermal stability.

Suits builders who want adjustable freeze

Enthusiasts who prefer to mix their own ratios and match the fluid to specific loop requirements will benefit from the concentrate format. Users needing a ready-to-pour fluid or a non-UV colour should consider a different product.

One bottle yields up to 50 parts coolant when mixed

At typical dilution ratios the 250 ml concentrate provides generous volume for large or multiple loops. The fluid remains stable in pressurised environments up to 390 °C and down to –50 °C, giving wide thermal headroom before performance limits are reached.

Questions about this item

Do I need to buy distilled water separately to dilute this 250ml concentrate before use?

Yes, the concentrate must be mixed with distilled water; the supplier recommends Mayhems Ultra Pure H2O for best results.

Will this UV Green coolant protect the nickel-plated blocks and aluminum radiators already in my loop?

The inhibitor package is proven to ASTM standards and protects copper, brass, steel, nickel and aluminum from corrosion and scale build-up.

How can I confirm the coolant is circulating correctly after I fill the loop?

The fluid is UV reactive, so a UV torch will show bright green flow through transparent tubing and reservoirs.
