Beschreibung
Zusammenfassung:	A fitting for a tube (70) or pipe capable of functioning a high pressures having a first fitting component (12) adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules (20,22) and a second fitting component (16) that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device (20,22) against pressure. The retaining portion (103) can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition. A further aspect of the invention includes a first fitting component (12) in which an exterior portion of the component is work hardened radially outward from the tube gripping device. The fitting may optionally be provided with a structure to effect the pull-up by torque functionality.
