Abstract: A pipeline has a fitting with a wedge-shaped plug pressed into a wedge-shaped fitting recess by a retaining ring to block flow through the fitting for pressure testing. The plug has an extractor plate fastened to the plug through a center of the retaining ring so the retaining ring can rotate relative to the plug and extractor plate. But the extractor plate is a predetermined maximum distance from the plug and is larger than the center opening of the retaining ring to captivate the retaining ring between the plug and extractor plate. That limits the retaining ring motion along the port's axis. Threading engagement between the retaining ring and port allow the retaining ring to push the plug into the fitting in a first rotation direction while rotation in the opposite direction allows the retaining ring to push the extractor plate and the connected plug out of the fitting.
