ABSTRACT OF THE DISCLOSURE Liquid piping saddle assemblies in few embodiments, all having significant interchangeable parts are available for con- necting branch pipes, i.e. laterals, to main pipes, i.e. mains. Each assembly has only one gasket of elastomer which seals both the lateral and the main and which integrally comprises essentially two cylinders. Each gasket of elastomer integrally includes a smaller hollow cylinder to snugly and sealably receive a lateral and a larger hollow cylinder to abut and to seal a main about the exterior of a hole made in the main of a diameter substantially matching the outside diameter of the lateral. Each gasket has a transitional volume structure of the gasket between the integral smaller hollow cylinder and the larger hollow cylinder. On the interior of this transitional volume structure is an integral interior circular abutment having an inner diameter substantially matching the inside diameter of the branch pipe, i.e. the lateral. On the exterior of the transitional volume structure is an integral exterior abutment structure having an inside diameter to match the inside diameter of a hollow cylindrical metal casting and an outside diameter to match or exceed the outside diameter of the same hollow cylindrical metal casting. Integral interior rings, semicircular in cross section, are formed in some gasket embodiments inside the smaller hollow cylinder to assist in sealing about the exterior of an inserted branch pipe, i.e. lateral, which is inserted until contacting the interior integral circular abutment. The exterior of the smaller hollow cylinder has an outside diameter to match the inside diameter of a hollow cylindrical metal casting in all embodi- ments. In some embodiments the thickness of the smaller hollow cylinder is reduced and an adjustable hose clamp is fitted to its exterior surface above the hollow cylindrical-metal casting. Opposite sets of spaced, upwardly sloping, receiving ears are integrally cast with the hollow cylindrical metal casting. Between these receiving ears, the threaded ends of bolts are received, and on the extending threads, beyond the ears, washers and nuts are positioned. The bolt heads are different with one head having a tee bar welded to an adjustable length metal strap and another head having two spaced adjacent tee bars welded at their ends, with one of these spaced tee bars, the outer one, being welded to the other of the two threaded bolts. The adjustable length metal strap is threadedly passed through the space between the spaced adjacent tee bars. When a proper length is determined, the metal strap is bent back in the opposite direction over the spaced tee bar and directed back alongside the metal strap, which is to partially encircle the main pipe, while and after the tightening of the nuts occurs to complete the sealed connection of the saddle assembly to the branch and main pipes, i.e. to the lateral and main.
