ABSTRACT:
A tank connector assembly including a metal spud member having an internally threaded portion and a cylindrical wall portion. An insert member of polymer material having a cylindrical wall portion. The insert member is mounted inside the cylindrical wall portion of the spud member. A bonding member of polymer material fits the cylindrical wall portion of said bonding member positioned between the external surface of the cylindrical wall portion of the insert member and the internal surface of the cylindrical wall portion of the spud member. The cylindrical wall portion of said bonding member being securely bonded to both the insert member and the spud member. In a preferred embodiment, the polymer material of the bonding member is malcated olefin. The bonding of the cylindrical wall portion of the bonding member to the polymer insert and the steel spud will prevent or at least substantially reduce any tendency of the water in the tank to leak past the outer surface of the insert member which, in turn, prevents water from coming into contact with the wall of the steel tank. Such contact if allowed to occur may cause corrosion of the steel tank. The bond between the outer surface of the cylindrical wall of the bonding member and the steel spud prevents water from coming into contact with the steel spud to thus prevent corrosion of the spud.
