Concentrated coolant for custom loops

This 250 ml concentrate is designed for enthusiasts building custom water-cooling loops who want to mix their own dilution ratio with distilled water. It targets users seeking maximum thermal performance and long operational lifetime from a glycol-based fluid.

Dilution flexibility and temperature envelope

The concentrate lets you set the final boiling and freezing points by adjusting the mix ratio with pure water. The base glycol blend is rated for continuous use in pressurised environments up to 390 °C and down to –50 °C, defining the practical thermal window of the finished coolant.

250 ml yields up to 50 parts finished fluid

One bottle can produce up to 50 parts of ready-to-use coolant when diluted, giving ample volume for large loops or multiple fills. It runs out when the reservoir is empty; the concentrate itself does not scale to industrial-scale systems without purchasing additional bottles.

Questions about this item

How much concentrate should I use and what volume of finished coolant will I get?

The 250 mL bottle is a concentrate that you dilute with distilled water at your chosen ratio, so the final coolant volume depends on the mix you select.

What temperature range can the mixed coolant handle inside a pressurised loop?

The glycol blend is rated for continuous operation up to 390 °C and down to –50 °C in a pressurised system.

Does the concentrate work with standard G1/4 fittings and common tubing materials?

The inhibitors protect copper, brass, steel, nickel and aluminium components, and the fluid is compatible with PETG tubing used with G1/4 fittings.
