  • ROLL FORMED CONDUIT FITTING
    Publication number: 20150107323
    Abstract: A tool roll forms an end of a thick walled conduit so that a conventional compression fitting may be used. The tool can include a forming roller with two ridges to make two ferrule-receiving seats in the conduit and a pair of edges forming witness lines that indicate when the seats have been fully formed by the tool. In addition the witness lines are located to show when a conduit had been fully inserted into a fitting and when the fitting has been fully made up.
