Abstract
A fluid interface between fluid conduits (14, 56) defined in two members (12, 52) attached in surface (20)-to-surface (58) contact with an O-ring seal (64) resiliently received in a counterbore cavity (62) is provided. A test passage (54) is provided from the cavity to the exterior, which will be blocked by the seal and will allow limited fluid from the cavity to the exterior in the absence of the seal whereby the presence or absence of fluid flow through the test passage is indicative of the absence or presence, respectively, of a properly installed seal.
