ABSTRACT In a rotary hermetic compressor, a suction tube seal is provided between the cylinder and the suction tube. The suction tube end extends through the housing of the hermetic compressor and is sealingly secured thereto such as by welding. The compressor cylinder, which is located in the housing has an aperture in the cylindrical wall thereof for receiving the end of the suction tube extending into the housing. The inside diameter of the aperture is greater than the outside diameter of the suction tube so that the suction tube is slidably axially received in the aperture. The suction tube is sealed to the cylinder by flexible sealing means which is interposed between the outside of the suction tube and the inside of the aperture. The sealing means is preferably an O ring constructed of oil resistant, flexible rubber material.
