The EK-CryoFuel is a new revolutionary coolant for PC liquid cooling systems. EK-CryoFuel is the most chemically stable coolant that provides enthusiasts and gamers with the best possible level of performance and thermal efficiency with emphasis on color stability. EK-CryoFuel coolant is a pure, non-toxic coolant based on the patent pending chemical formula, which prevents the creation of any sediments in the liquid cooling loop. Liquid cooling users can rest assured that the EK-CryoFuel coolant, with its very low viscosity, will not clog or damage their water blocks and other parts of the loop when used with EK-DuraClear or EK-ZMT tubing. Does not contain ethylene glycol or a bittering agent. Model: TR-81325-99436
