ABSTRACT:
Liquid piping saddle assemblies, in two sizes, to connect to branch pipes of 4 inch and 6 inch diameters, and to all sizes of main pipes, in respect to each assembly has only one elastomeric gasket, which seals both the branch pipe and the main pipe. Each gasket integrally includes a smaller hollow cylinder to surround and sealably receive an end of a branch pipe, and a larger hollow cylinder shaped to abut and to seal the outside of a smallest main pipe without bulging and the outside of a larger main pipe upon bulging, about the exterior of a hole made in the main pipe. In the gasket sealing surface at the main any imaginary transverse line lies in a geometric plane which is perpendicular to the common centerline of the gasket. Each gasket has an interior circular abutment to stop the insertion of the branch pipe, and an exterior abutment to position a hollow cylindrical metal casting, which fits over the smaller hollow cylinder. An adjustable holding means partially encircles the main pipe and engages the hollow cylindrical metal casting forcing it against the exterior abutment, thereby firmly holding the gasket against the main pipe.
