Abstract
Abstract A fitting and pipe combination, wherein fittings are applicable directly to the side walls of and over openings through pipe and especially plastic pipe and the like, either for mending the same or for establishing a lateral fluid connection. The fitting provided is a saddle-shaped element which more than half way embraces the tubular pipe body so as to pressure itself onto the pipe. And, fluid adhesive and/or fluidized fitting and pipe material is hydraulically pressured into a channel seal that encompasses the openings through the pipe and fitting, to subsequently solidify and bond the fitting to the pipe, and so as to establish a strong and durable leak-proof joinder.
