  • Patent number: 5655571
    Abstract: Thin metal adaptor rings fit within elastomeric seal rings holding an orifice plate within a fitting. The thin metal rings have an inside diameter equal to the inside diameter of the pipe line and fitting. Therefore, the inside diameter is maintained without variations as previously resulted from protrusion or recess tolerances of the elastomeric seal rings. The seal ring is modified with notches to hold the thin metal adaptor rings in the desired position.
