  • Patent number: 4342462
    Abstract: An adjustable seal member for effecting a leak-proof junction between a conduit and an opening in the sidewall of a manhole well in an underground sewer installation. The seal member, made of elastomeric material, is in the form of a flanged sleeve which is disposed about the periphery of the conduit and which is clamped over the conduit by means of a steel strap clamp. The flange is embedded in the concrete or cement of the manhole well structure in the edge of the opening in the manhole. The sleeve is adjustable to diverse conduit sizes within a range by having a plurality of increasing internal diameter portions for fitting conduits of different outer diameters within the range to insure relatively close fit between the internal surface of the sleeve and the external surface of the conduit.
