Abstract
An apparatus and method are provided for pressure testing pipe and fittings systems. A seal has a disk portion and a flange portion. The seal is permanently attached to the inside of a fitting on the distal end of the pipe section to be tested, thereby blocking fluid flow. The section is installed and tested by conventional means. After testing, a pull-tab formed in the seal is removed to permit fluid flow through the seal. Subsequent sections can then be installed and tested.
