Abstract
A fitting made up of a body, a ferrule and a nut. The ferrule has a reduced size cylindrical member that is received in an end of a thin wall tube. The nut and the deformable ferrule are placed over the tube. The nut is wrenched onto the body, which deforms the ferrule at the ferrule groove displacing material of the ferrule inwardly against the tube, bringing the inner surface of the ferrule into sealing engagement with the outer surface of the tube and the inner surface of the tube with the outer reduced cylindrical surface of the body and at both faces of the ferrule. A seal is thus accomplished at the inside surface of the ferrule, forcing the tube into engagement with the reduced size member of the body, thereby reinforcing the tube.
