Abstract:
An improved gasket of integrally molded elastomer for sealing a space around a pipe installed in an opening in a wall having outer and inner sides, comprising:an annular base portion having inner and outer interior shoulders diverging laterally from a mid-region to respective outer and inner distal ends thereof; an annular flange portion, extending radially outward from said base portion, formed to abut the outer side of said wall around said opening; annular keeper means extending radially outward from said base portion and axially spaced from said flange portion to form a continuous groove for sealingly receiving the interior periphery of the wall opening, said keeper means being tapered axially from the outer periphery thereof to the distal end of said inner interior shoulder for snap-fitting against the inner side of the wall when fully inserted in the opening; annular web means extending radially inward from said mid-region for deflecting in compression against said inner interior shoulder by the installed pipe; and toroidal means of circular shape in radial cross section to the inner periphery of said web means for compression against said inner interior shoulder by the installed pipe.
