Patent ID: 7014222

Claim:
A high pressure fluid fitting assembly for a fluid-tight coupling of a tube member, having a conduit, to a connector member having a receiving port defined by an interior sealing wall and a bottom end wall, and formed for sliding receipt of said tube member until a distal end thereof seats against said bottom end wall, said connector member further defining a passage extending therethrough and terminating in the receiving port, said fitting assembly comprising: a contact device having proximal surface and an opposite distal surface facing toward said connector member, and having an interior alignment wall defining an alignment passage extending from the proximal face to the distal face for sliding receipt of the tube member therethrough; and a ferrule device having a proximal tube engaging portion, an opposite distal sealing portion and a tube receiving passage extending from the tube engaging portion to the sealing portion and formed for receipt of the tube member therethrough, said tube engaging portion includes at least one longitudinally extending slot, and being formed and dimensioned to contact the contact device alignment wall and said sealing portion being formed and dimensioned to contact the connector member sealing wall such that when a compression force is increasingly applied to the contact device in the direction toward the connector member, the contact device alignment wall contacts the ferrule device tube engaging portion in manner causing an interior gripping surface thereof to increasingly radially grip the tube member for movement of the ferrule device and the contact device, as a unit, toward the connector member to increasingly urge the ferrule device sealing portion into fluid sealing engagement with the connector member sealing wall and to fluidly couple the tube member conduit to the connector member passage, and increasingly urge said distal end of the tube member into seated engagement with the bottom end wall of the connecter member.
