    looks like a test port brazed in suction line by installer. Waste of part/money.

    Factory installed port. Lots of units have them.

    It is likely an external equalizer port connection for use with a thermostatic expansion valve.

    Its factory installed and is used to enter, and subsequently relieve, the shipping pressure in the coil (usually just dry nitrogen).

    Contractors use this to quickly verify that the boxed coil they are buying has held its shipping pressure upon pickup at the loading dock. If there is low or no pressure left in the coil then he will not accept it.

    After installation it serves no particular purpose.
