Assembly for Engaging the Interior of a Pipe

An assembly for engaging an inner wall of a pipe, the assembly having a longitudinal axis and comprising:

• an end plate and an annular ring adapted to be coaxially aligned along the longitudinal axis of the assembly, when in use;
• the annular ring comprising a face having a flat portion provided at least on an outer perimeter thereof and a flange member extending from the face, the flat portion being on a plane perpendicular to the longitudinal axis of the assembly;
• the end plate comprising a surface including a slot adapted to be aligned with and receive the flange member of the annular ring therein, wherein the surface of the end plate includes a beveled edge on an outer perimeter thereof;
• a notch defined by the flange member of the annular ring, the flat portion of the annular ring, and the beveled edge on the surface of the end plate;
• a resilient sealing member provided in the notch and seated on the flange member of the annular ring prior to the assembly engaging the inner wall of the pipe;
• and
• an urging mechanism adapted to urge the annular ring against the end plate, whereby, when in use, the flange member of the annular ring is received within the slot of the end plate and the resilient sealing member is compressed within the notch and deformed radially outwardly to engage with the inner wall of the pipe.
