Apparatus and method are disclosed for externally testing flanged or hubbed connections used on fluid conducting conduits. A ring gasket fits between the faces of the connecting flanges or hubs to effect a fluid tight seal. A test ring also fits between the faces of the hub or flange connection in a manner so as to form a space between the test ring and the ring gasket. Seal means closes the space between the test ring and the faces of the flanges or hubs. The outside diameter of the test ring is confined within fastening means which secures the hubs or flanges together. Fluid under pressure, used to test the effectiveness of the ring gasket seal, is applied to the space between the ring gasket and the test ring seal means. The pressure in that space falls when the ring gasket is defective but remains constant if the ring gasket is sound. Following the test, fluid pressure is bled off the space between the ring gasket and the test ring seal means. The test fluid pressure is applied to and bled from such space through a pressure port or passageway formed in the test ring or in one of the flanges or hubs.
