An electrofusion saddle is a type of fitting used for joining polyethylene (PE) pipes through electrofusion welding technique. It is designed as a "saddle" shape, meaning it wraps around the existing pipe and makes a connection to a new pipe via an electrofusion coupling. The electrofusion process involves heating the inside surface of the fitting and the outside surface of the pipe simultaneously using an electrical current. This melts the PE material and forms a permanent bond between the fitting and the pipe. Electrofusion saddles are commonly used in water supply, gas distribution, and in
