ABSTRACT:
A liquid tight connector for non-metallic conduit is formed of a one piece body having a through bore. A sleeve extends inwardly from one end of the body and a threaded nipple extends inwardly from the other. Projecting transversely from the inner end of the nipple is a flange. A ferrule skirt extends from the flange toward the sleeve end of the body to define an annular channel concentric with the sleeve. An internal buttress thread is formed on the inner wall of the skirt. An end of a length of conduit is slipped over the end of the sleeve and into the mouth of the channel. The connector is rotated relative to the conduit, with the thread engaging an outer wall of the conduit to tightly draw the channel over the conduit. An outward flare is provided at the flange end of the sleeve to compress and seal the conduit.
