Claim Text:
1. A peripheral sealing gland to form a seal, between an elongate member and a substantially flat surface having an aperture into which said elongate member extends, said peripheral sealing gland comprising; an at least in part frustoconical shaped skirt through which said elongate member is to pass and defining at an upper periphery of the skirt, a deformable upper seal configured to deform about and form a first seal to a periphery of said elongate member, a flange having an outer surface and an inner surface and a radially outer edge, the flange depending from a lower periphery of said skirt, and the flange including two or more concentrically arranged endless lip seals extending from the inner surface, and having a plurality of flange apertures disposed entirely between consecutive ones of said lip seals; said skirt and said flange being integrally formed; a substantially rigid ring having a plurality of ring apertures, said ring apertures corresponding to, and co-locatable with, at least some of said flange apertures, said rigid ring able to bear on said outer surface of said flange without substantial deformation, so as to apply a substantially consistent pressure to said endless lip seals to form a second seal against said flat surface when said rigid ring is fastened to said substantially flat surface by fasteners to capture the flange therebetween; said skirt having, toward said flange, a retention flange forming a circumferential pocket to removably receive said rigid ring and to permit adjustment of said rigid ring relative to said flange to co-locate said flange apertures with said ring apertures; wherein a diameter of said flange apertures is smaller than a diameter of said ring apertures, so that said flange is configured to form, at said flange apertures, a third seal against said fasteners.
