ABSTRACT:
A device for use in evacuating fluid from a tubular refrigerant line comprises an elongated hollow tubular frame, which has a line seating extension attached to an open end of the frame and spaced from the end for engaging a refrigerant line in a position centered at right angles to the central axis of the elongated tubular frame. A reciprocating hollow inner tube is mounted for movement within the hollow frame and it has a piercing point on one end for movement into and out of engagement with a refrigerant line seated in the line seating extension. A resilient seal surrounds the piercing point for movement with it; and a cam mounted on the frame is used to move the inner tube to cause the piercing point to engage and pierce a refrigerant line located in the line seating extension.
