Patent ID: 8741019

Claim:
A sealing arrangement comprising: two opposing mounting flanges each including a flange face, said flange faces arranged in a confronting facing relationship; a seal flange installable between said flange faces and configured to seal between said confronting mounting flanges, said seal flange including a seal flange body having a flat annular portion with opposing seal flange faces configured to be received between said mounting flange faces; and a seal flange circumferential outer edge extending between said opposing seal flange faces; an annular electrically conductive elastomeric seal arranged on an outer circumferential edge of said seal flange body, said conductive seal including a continuous radial groove formed into a radially inner face of said seal; wherein said circumferential outer edge of said seal flange is received into said radial groove of said seal; wherein said electrically conductive seal has opposing seal leg members extending over said outer edge and each onto at least a portion of a respective one of said seal flange faces; wherein said electrically conductive seal is operative to conduct electric charge between said seal flange body and said mounting flanges; wherein said conductive elastomeric seal is provided as a separate molded component elastically retained on said circumferential outer edge of said seal body, said seal elastically stretched over and installed onto said seal flange circumferential outer edge by utilizing elastomeric properties of said seal; wherein said mounting flanges include a seal receiving and guiding contour; wherein said seal receiving and guiding contour, when said mounting flanges confront and mate, form a continuous groove geometry complimentary to geometry of outer faces of said seal legs, said guiding contour sized and configured to elastically compress said seal when said seal flange body is mounted between said mounting flanges; wherein said groove geometry of said seal receiving and guiding contour includes: a first groove sidewall formed in a face of a first one of said mounting flanges; a second groove sidewall opposite said first groove sidewall, said second groove sidewall formed in a face of a second one of said mounting flanges; wherein said groove geometry includes a mouth between said opposing mounting flanges opening radially inwardly into an interior fluid carrying aperture of said mounting flanges; wherein said groove geometry has a circumferential outermost bottom wall formed in at least one of said mounting flanges and arranged radially outwardly from said mouth; wherein said opposing seal legs have outer seal faces with a geometry complimentary to said groove sidewalls of said mounting flanges.
