ABSTRACT:
An isolation diaphragm assembly designed to be installed in a standard tee, Y or coupling in a conduit to isolate one portion of the conduit from another. In its initially installed condition, the isolation diaphragm assembly provided a seal for isolating portions of conduit systems for pressure testing. Once the testing procedures are complete, the test diaphragm, being larger in diameter than the interior diameter of the conduit, is flexed into a saddle shape to permit its removal from a gasket and due to the decreased dimension, may then be drawn out of the conduit, leaving a fully unobstructed flow path.
