Abstract: Devices and methods for coupling fluid conveying piping (12) in an arrangement to provide a one or more branch connections. A mechanical fitting includes a lower housing (110a) and an upper housing (110b) coupled to one another to define an interior space (112) for housing a tubular pipe segment (12). At least one insert (200) for insertion in one of the upper or lower housing includes a tubular body (200b) that defines a fluid flow passageway (202) and a base (200a) that engages an opening (14) in the pipe segment (12). The base and housings are configured to engage one another to prevent rotation of the insert (200) with respect to the housing (110).
