ABSTRACT:
A hermetic compressor unit comprising a hermetic casing containing a compressor including a cylinder block having an arcuate surface engaging the inner surface of the casing and a suction tube assembly for connecting the compressor to a refrigeration system. The suction tube assembly comprises a connector including an end portion extending into an opening in the casing in alignment with a suction passage in the cylinder block. A tubular sleeve member chosen from the group of metals having a higher ductility than steel has a first portion arranged in the suction passage and a second compressible portion arranged in the connector. A steel tubular fitting includes a first portion press fit into the first portion of the sleeve member and a second portion dimensioned to engage and collapse the compressible second portion of the steel fitting to simultaneously effect a fluid tight seal in the suction passage and connector thereby sealing the compressor casing and suction tube assembly to the compressor.
