FIELD: physics; testing.
SUBSTANCE: present invention relates to test engineering and is particularly meant for testing pipe fittings. Technical outcome is achieved due that, the apparatus for testing hollow objects contains immovable and movable face plates fitted on a stand, each of which has a groove, which interacts with the landing projection of a stopper with a central channel and with an elastically deformed ring, which seals the inner cavity of the object. The movable face plate has an inlet channel for test medium. According to the invention, each stopper is equipped with a tightener, which interacts with the elastically deformed ring, sealing the inner surface of the object, and controlled by screws passing through the body of the stopper. The screws, passing through the body of the stopper, are uniformly arranged around, and there are at least two of them.
EFFECT: provision for reliable sealing of connecting pipes of the test object during testing, with possible deviation of the geometry of their inner surfaces.
