Size of heater Core hose

Hey, does anyone know the inside diameter of heater core hose where it connects to to the firewall I'm looking to connect both of them to bypass them and see if the rad hold pressure I'm pretty sure it's about 5/8

Looks like 5/8 is correct. According to sizes on Autozone's website. Heater Core is 0.625 and heater core hose is 0.63, close enough.
