Face plate gasket

Claim 1

In combination, a plumbing fitting having a substantially horizontal conduit terminating in a substantially vertical peripheral face transverse to said conduit, and a face-plate gasket of pliable resilient material for sealing a joint between said face of said fitting and a face plate to be positioned in adjacent communicating relationship with said fitting, said gasket comprising a peripherally extending radially relatively wide and axially thin flange generally parallel to said peripheral face of said fitting and adjacent thereto, said flange having spaced inner and outter margins having opposed sealing faces between them, with one said sealing face being adjacent said substantially vertical peripheral face of the fitting and said other face being adapted to be engaged by a face plate, a plurality of radially spaced apart, endless, peripherally extending beads extending from one said flange face, and generally horizontally extending support means integral with and extending transversely of said flange at said inner margin thereof, said integral support means comprising a peripherally extending lip having inner and outer surfaces, a bead on the outer surface of said lip remote from said flange, said bead engaging said conduit and distorting said lip from an initial position prior to insertion in which said lip extends generally perpendicularly to the plane of said flange of a second inserted position in which said lip is squeezed inwardly by said conduit to thereby produce a reactive force against the conduit wall, whereby said gasket is supported with the flange in a substantially vertical plane by said integral lip.
