Resilient plug apparatus and method of use

A system for blocking the flow of media through a pipe having a longitudinal axis and an annular wall defining an outer wall surface and an inner wall surface, wherein the inner wall surface defines an inner pipe diameter, the system comprising:

• a fitting configured to be secured to and surround a section of the pipe, wherein the fitting defines a channel that is configured to provide access to an area on the outer surface of the pipe to facilitate forming an aperture in the pipe wall;
• a plug assembly comprising:
• an upper plate;
• a lower plate;
• a cylindrical resilient plug disposed between the upper and lower plates, the resilient plug having an outside diameter larger than the inner pipe diameter;
• and
• a shaft configured to selectively rotate causing a distance between the upper plate and the lower plate to change,
• wherein the plug assembly is configured to be inserted through the channel and the aperture formed in the pipe annular wall.

A system for blocking a flow of media through a pipe having a longitudinal axis and an annular wall defining an outer wall surface and an inner wall surface, wherein the inner wall surface defines an inner pipe diameter, the system comprising:

• a fitting sized to surround a section of the pipe, the fitting defining a channel providing access to a fitting area on the pipe;
• a plug assembly including:
• an upper plate;
• a lower plate;
• a plug disposed between the upper and lower plates;
• and
• a shaft engaging the lower plate, the shaft being movable to cause the lower plate to move with respect to the upper plate,
• the plug assembly being insertable through the channel and through an aperture in the fitting area wherein the lower plate includes a portion with a cross-sectional profile that restricts rotation of the lower plate when the profile is engaged by the fitting.
