ABSTRACT:
A sleeve connecting a refrigerant pipe to a sealed compressor container has a reduced outer dimension and an inner step that accommodates the refrigerant pipe. An end of the refrigerant pipe abuts the inner step to accurately locate the refrigerant pipe to permit the refrigerant pipe to be secured in an desired relationship with the sleeve. The sleeve is attached to the container with increased accuracy and less chance of damage to the container through deformation during the attachment process. The sleeve and container may be composed of iron, while the refrigerant pipe may be composed of copper, so that the more rigid sleeve can accurately couple the less rigid refrigerant pipe to the container.
