Gorter--Mellink counterflow limits (at zero net mass flow) have been measured from 0.01 bar to about 3 bar in relatively wide ducts of rectangular (0.05 cm wide) and circular cross section (0.446 cm inner diameter). The observed limiting temperatures did not show metastable superheating of He II. Instead, they were controlled by the equilibrium state phase boundaries of the superfluid $sup 4$He. Small departures from the related maximum temperature differences were in part caused by fluid acceleration and finite thermometer sizes, respectively. The measured limiting heat fluxes agree with the prediction based on the equilibrium state limits of the Gorter--Mellink temperature differences. (auth)
