Patent ID: 7914048

Claim:
A pre-assembled, liquid tight, electrical conduit coupling device for connecting a first electrical conduit to a second electrical conduit or to an opening of an electrical device with easy installation, said pre-assembled, liquid tight, electrical conduit coupling device comprising: a ferrule having a first end portion and a second end portion, a radial flange extending from said first end portion, said second end portion having external threading adapted to cooperatively mate with said first electrical conduit, said radial flange having at least one axially-extending protrusion; a tubular connector body defining a tubular space having a first end of a reduced diameter and a second end of an enlarged diameter, said reduced end having external threading adapted to connect to a second electrical conduit or to an opening of an electrical device, said enlarged end having external threading, an internal radial ledge within the tubular space between said first end and said second end, and at least one axially-extending depression that correspondingly engages said at least one axially-extending protrusion of said radial flange of said ferrule for cooperatively engaging said at least one protrusion of said radial flange to restrict relative rotation between said ferrule and said connector body; a first sealing ring; and a compression nut having internal threading that correspondingly engages said external threading of said enlarged end of said tubular connector body, such that said first sealing ring is concentrically nested within said compression nut to provide a liquid tight seal against said first electrical conduit in response to engagement of said external threading of said enlarged end of said tubular connector body to said internal threading of said compression nut to compress said first sealing ring against said second end portion of said ferrule and said first electrical conduit.
