Abstract: A preassembled pipe coupling and method for joining pipe segments in an end-to-end relationship. The coupling (100) includes three identical housing segments (110) joined end to end. Each housing segment (110) includes a pipe engagement surface defining a radius of curvature. The radii of curvature of the three housing segments (110) are identical. The third housing segment is connected to the first and second housing segments to define a first configuration and a second configuration of the coupling, in which the radii of curvatures are the same in the first and second configurations. In the first configuration, the three housing segments (110) are radially located about an annular gasket (400) to permit insertion of the pipe segment into the gasket (400). In the second configuration, the three housing segments are radially located about the annular gasket such that the gasket is compressed to form a fluid tight seal and the pipe engagement surfaces engage the outer surface of the pipe segment.

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).
