Abstract
A braze-free connector suitable for use in a refrigeration system that includes a connector body having a circular opening passing therethrough. The opening has a converging section that tapers downwardly from the entrance to the opening toward the back of the opening. A ferrule is slidably mounted upon a refrigerant tube which is inserted into the opening to place a tapered collapsible section of the ferrule in contact with the tapered section of the opening. The non-collapsible section of the ferrule is keyed to a nut which in turn is mated with a male thread formed on the connector body whereby the collapsible section of the ferrule is forced into engagement with the refrigerant tube. A pressure sensitive sealant is pre-coated upon at least the collapsible section of the ferrule which is activated as the ferrule is forced into engagement with the refrigerant tube.
