An apparatus is 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.

A test fitting for use in pressure testing pipe and fitting systems during the installation thereof, comprising: a water impermeable barrier adapted to block fluid flow through said pipe and fitting system; means for sealably and permanently installing said barrier into a fitting in said pipe and fitting systems, said means for installing comprising elastic, fluid resistant means about the periphery of the barrier adapted to press outwardly from the barrier and seal the barrier against an interior wall of said fitting; and, frangible, removable seal means in said barrier permitting fluid flow therethrough when broken and removed, a portion of said barrier remaining in said fitting in said pipe and fitting systems, said portion of said barrier being insufficient to substantially impede fluid flow through said fitting.
