Abstract

A ferrule subassembly for a conduit fitting includes first and second ferrules. The first ferrule includes a front body portion defining a forward tapered surface, a rear body portion defining an interior camming surface, and a retaining extension joined with the rear body portion radially outward of the camming surface and extending axially rearward and radially inward from the inner axial portion. The second ferrule includes a front portion having a tapered forward contact surface adjacent the first ferrule camming surface, an outer radial portion extending axially rearward of the forward contact surface, and a recessed portion axially rearward of the outer radial portion. An end portion of the retaining extension is received in the recessed portion of the second ferrule to retain the second ferrule with the first ferrule as a discontinuous subassembly.
