An evaporator cuff for use with a pipe freezer apparatus. The evaporator cuff includes a hose connector attached to an evaporator body. The evaporator body has an inner wall configured to engage the outer surface of a pipe, and an outer wall spaced apart from the inner wall. A chamber is defined between the inner and outer walls, first and second side walls, and first and second end walls. A plurality of baffles are located in the chamber and arranged to define a series of conduits for creating a flow path through the chamber for refrigerant to flow along. The walls are arranged so as to form a serpentine flow path from the evaporator inlet to the evaporator outlet. |
