Patent ID: 8910980

Claim:
A liquid-tight fitting comprising: a ground element including a ferrule portion and a tube portion that is configured to receive an inner surface of a wall of a conduit, wherein a first end of the tube portion extends from the ferrule portion, and wherein a second end of the tube portion, which is located at an opposite end relative to the first end, includes an inward tapered portion, wherein a circumference of the inward tapered portion increases as the tube portion extends from the second end, and wherein the tube portion includes one or more protruding elements that each protrudes from the tube portion and provides grounding to the conduit, wherein the one or more protruding elements are located between the first end and the second end of the tube portion, and wherein the ferrule portion includes a lip portion; a threading element including a first shaft having a circumference sufficient to receive the ferrule portion of the ground element, wherein the first shaft includes threads; a sealing ring including a first opening having a lip, and a second opening defined by a tapered portion relative to a main body of the sealing ring, wherein the tapered portion is contoured to seat against the lip portion, and wherein a neck of the sealing ring is formed between the lip and the main body and the sealing ring includes teeth disposed on a surface of an inner wall of the sealing ring; and a nut including threads to be received by the first shaft, wherein an interior wall of the nut is contoured to receive the sealing ring such that the lip of the sealing ring protrudes from an open portion of the nut, and wherein as the nut is continuously threaded with the first shaft of the threading element, the teeth of the sealing ring are compressed onto an outer surface of the wall of the conduit to provide a liquid-tight seal based on the tapered portion of the sealing ring meeting with the lip portion of the ferrule portion and a pulling of the open portion of the nut against the neck of the sealing ring.
