Liquid phase pvT properties of 1,1,1,2,3,3,3-heptafluoropropane (R 227ea) and HFE 7100 were measured precisely using a constant-volume cell. The pvT property of R 227ea was measured in the temperature range of (266 to 313) K and the pressure range of (0.823 to 17.014) MPa. The pvT property of HFE 7100 was measured in the temperature range of (275 to 303) K and the pressure range of (0.273 to 19.135) MPa. The temperature standard uncertainty was estimated to be 2.3 mK, the pressure standard uncertainty was estimated to be 15 kPa and the density relative standard uncertainty was estimated to be 0.0015. The experimental data for R 227ea was compared with an equation of state with a root-mean-square relative difference of 0.0003. A new equation of state for liquid HFE 7100 was developed and with the root-mean-square relative difference of the HFE 7100 experimental data from the equation of state being 0.00002
