ABSTRACT:
A sleeve adapter (S) for locating a throughpipe (24) in a structural member (18). The sleeve adapter (S) comprises an annular apertured hub (2) having a central axis .alpha., a first annular surface (4) adjacent a first face of the hub (2) sloping inwardly toward the axis, a second annular surface (8) adjacent a second face of the hub (2), and a third annular surface (12) intermediate the first (4) and second (8) surfaces of a smaller diameter than the second annular surface (8). The adapter (S) also comprises a mechanical joint gasket (6) engaging the first annular surface (4) which locates a throughpipe (24) concentric with the central axis, a push-on gasket (10) engaging the second annular surface (8) which locates a sleeve pipe (14) concentric with the central axis, and a pressure device for urging the mechanical joint gasket (6) against the first annular surface (4) and the throughpipe (24). The sleeve adapter (S) optionally comprises a circumferential flange (16) adjacent the second face of the hub (2) which prevents liquid from seeping through the structural member (18).
