  • Protective bushing to enclose the end of a conduit liner
    Patent number: 4122870
    Abstract: A pipe, having a vulcanized, elastomeric liner within it, is finished off with a bushing at each end, the bushing being within the liner with its end being outwardly flared, as a bell mouth, to completely confine the end of the liner between the bushing and pipe. An unvulcanized elastomeric liner, characterized by a slight increase in volume when vulcanized, is used with the liner portion between the pipe and liner producing a very tight fit due to such expansion.
