That's NOT for a/c its an emissions test port. The a/c ports are on the other side of the truck. One on the accumulator, and one on a line near the condenser.

Evap stands For Evaporative Emmisions System. The Evaporator is a component of the A/C system. The pic of the component you have posted is for testing the Evap systems of the emissions. Its is used to check for leaks. Evap is for the removal of fumes created by gasoline in the gas tank. It keeps the fuel tank at the correct pressures.
