Abstract: A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position. Flow through the testing device is allowed with the rotary valve closed and the tubular valve stem in an open position. With the rotary valve open, flow through the tubular valve stem is permitted when the tubular valve stem is in either the first or second position to provide multiple drain and fill options.
