FC-75 is a perfluorocarbon derivate of tetrahydrofuran with the chemical formula C8F16O. It is practically insoluble in water.

It is one of the 3M Fluorinert fluids. It is used as an inert coolant fluid in electronics and other applications, and as a solvent.

A similar perfluoro coolant and solvent is perfluorohexane.
