PE pipes can be joined by butt fusion thus avoiding the need for a fitting. Some spigot end fittings are produced specifically for butt fusion to pipe. These must be specified to match both the pressure rating and the SDR of the pipe. It is normally not acceptable to use a butt fusion fitting of a different SDR rating to that of the pipe even if the pressure rating of the fitting is equivalent or higher than that of the pipe.
