  • Seal ring for orifice plate
    Patent number: 6843483
    Abstract: A seal ring for an orifice plate includes a metal annular body having an outer peripheral edge and an inner peripheral edge. A first sealing element retainer is integrally formed with and extends from a first side of the body. A second sealing element retainer is integrally formed with and extends from a second side of the body. An annular first sealing element engages the first sealing element retainer on the first side of the body. An annular second sealing element engages the second sealing element retainer on the second side of the body. The first sealing element and the second sealing element leave the outer peripheral edge of the body exposed to facilitate metal on metal contact between a carrier of an orifice fitting and the outer peripheral edge. The first sealing element and the second sealing element extend past the inner peripheral edge to form an orifice plate receiving groove.
