ABSTRACT:
The present invention provides a quick-connect pressure test apparatus. The apparatus includes a test plug having a set of sealing rings extending around a sidewall thereof for fitting within an inner diameter of a pipe. The test plug has a first end having a receiving cavity in communication with a central lumen that extends through the test plug to a second end thereof. A retainer is configured to sit on an end section of the pipe, having a plurality of retaining arms flexibly extending about an outer diameter of the pipe. A slide compressor is configured to receive the retainer within a cylindrical cavity, urging the retaining arms to frictionally engage the outer diameter of the pipe and maintain the test plug within the pipe. A plug handle or, alternatively, a pressure coupler may be received in the receiving cavity of the test plug.
