Abstract
A refrigerant connection includes a ferrule positioned within a threaded nut. The threaded nut is received on a connector body. A seal is positioned between the ferrule and the connector body. As the nut is turned on the connector body, the ferrule squeezes the seal. The seal is cylindrical such that sealing surfaces are provided at each axial end and at an outer periphery. In this way, the seal is not as sensitive to surface imperfections in the various components as was the case in the prior art.
