The electrical resistivity of the heavy-electron superconductor UBe13 has been measured at temperatures T between 0.1 and 300 K for pressures P to 16 kbar and in magnetic fields H up to 9 T. The temperature Tmax at which shows a maximum increases linearly with P at H=0 and with H2 for P=14.8 kbar. The resistivity, when normalized to its value at Tmax(P), scales as a function of reduced temperature T/Tmax(P) from 1 K to 1/41.4Tmax. At P=14.8 kbar, the magnetoresistance -[R(H)-R(0)]/R(0) behaves as a universal function of H/T for 1T6 K and 0
