ABSTRACT:
A flexible pipe saddle molded from a flexible resilient polymer includes a hollow, semi-cylindrical saddle portion adapted to overlie the external surface of a main pipe having a hole therein. The saddle is provided with a radially directed aperture with a radially, inwardly directed, circumferential flange extending about the aperture and extending into the hole in the pipe to locate the saddle relative to the hole in the pipe. The saddle is also provided with a hollow tubular sleeve having a stepped, internal cylindrical surface defining a stepped shoulder for limiting the insertion of a lateral pipe. A hollow tubular bushing of the same material as the saddle is removably disposed in the hollow tubular sleeve and has a radial thickness less than the radial dimension of the stepped shoulder so that a smaller diameter lateral pipe may be used and still abut against the stepped shoulder. A stainless steel skirt overlies the saddle portion and adjustable straps are provided for clamping the saddle portion to the main pipe and for clamping the hollow tubular sleeve to the lateral pipe.
