Abstract:
1. A test plug for use with a clean-out that defines a clean-out axis, the clean-out extending at an angle from a pipe section that defines a pipe section axis, the pipe section further defining an internal surface, said test plug comprising: a first plate having a top surface defining an opening; a second plate having a bottom surface defining an opening; a compressible ring-shaped sealing member defining a perimeter contact surface, the sealing member located between the first and second plates; a valve defining a valve end, the valve being configured to move along a valve axis within the opening defined in the top surface of the first plate; and an actuating member coupled to the valve and configured to move along an actuating member axis, wherein the actuating member axis extends at an angle from the valve axis, and wherein the actuating member is configured to move the valve between an open position, in which test media may be communicated through the opening in the first plate and through the opening in the second plate, and a closed position, in which the valve end seals the opening of the first plate and draws the first and second plates together such that the sealing member is compressed between the first and second plates and extends outwardly to seal against the internal surface of the pipe section.
