CONDUIT RETAINING STRUCTURE FOR CONDUIT FITTING

摘要

A conduit fitting preassembly includes a nut (210) and at least a ferrule (220). The nut has an interior wall extending axially from a forward end to a rearward end, and a first projection (212) extending radially inward from the interior wall. The ferrule is received within the nut and includes a second projection (222) extending radially outward of an outer surface of the ferrule. The first projection includes an outward tapered rear surface and the second projection includes an inward tapered front surface. The rear surface of the first projection is radially aligned with the front surface of the second projection, such that when the ferrule is in a forward-most position, the first projection interlocks with the second projection to prevent axial withdrawal of the ferrule from the nut.
