Peripheral sealing gland for elongate objects passing through a surface or beyond a pipe end

A method of providing a peripheral sealing gland configured to form a seal between an elongate member and a substantially flat surface having an aperture into which said elongate member extends, the method comprising:

• providing an at least in part frustoconical shaped skirt through which the 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 the elongate member;
• providing a flange having a radially outer edge and an outer surface opposite an inner surface, the flange being integrally formed with the skirt and depending from a lower periphery of the skirt, the flange having two or more concentrically arranged endless lip seals extending from the inner surface, and a plurality of flange apertures disposed entirely between consecutive ones of the two or more endless lip seals;
• and
• providing a substantially rigid ring configured to bear on the outer surface of the flange without substantial deformation, so as to apply a substantially consistent pressure to the two or more endless lip seals to form a second seal against the flat surface when the rigid ring is fastened to the substantially flat surface by fasteners to capture the flange therebetween, the rigid ring having a plurality of ring apertures corresponding to, and co-locatable with, at least some of the flange apertures to receive the fasteners;
• wherein the rigid ring is substantially non-deformable;
• wherein the skirt is provided to include, toward the flange, a retention flange forming a circumferential pocket to removably receive the rigid ring and to permit adjustment of the rigid ring relative to the flange to co-locate the flange apertures with the ring apertures;
• and
• wherein the flange apertures have a smaller diameter than the ring apertures, so that the flange is configured to form, at the flange apertures, a third seal against the fasteners.

• providing a resealable split extending from the upper seal to a peripheral edge of the flange;
• and
• providing a compression clamp having at least two opposing pressure application surfaces configured to seal the resealable split;
• wherein the rigid ring is substantially non-deformable.
