They consist of a threaded male end (1/2" npt for this application) for through the fire wall, and a threaded compression fitting on the other end that compresses a rubber gland around the cable sheath, making it leak tight, secure, and still encased in rubber for vibration/flex dampening. When I was active in the electrical business, we called them 'CGB' connectors. Not sure what their recognized trade term is today. You will need your cable diameter to select the correct gland internal diameter. For fastening in the fire wall, either thread a piece of phenolic block or use the locknut that comes with the connector, and simply put it on the other side of the fire wall. I think the threads are long enough.
