Abstract: A connecting device for providing a liquid tight connection between a conduit and a panel includes a tubular body with a central flange having a forward face and a rearward face, a rear tubular section extending axially from the rearward face and a tubular nose section extending axially from the forward face. This body also has an annular cover section and an annular passageway be formed between the cover section and the rear tubular section. At least one thread is formed on the cover section and projects radially inwardly. A sealing ring is mounted in the passageway adjacent the rearward face and provides a seal between the tubular body and an end of the conduit. A forward fastening device secures the nose section to the panel.
