Title: Apparatus for sealing flange joints

Abstract: In one exemplar embodiment, an injection ring is provided that fits tightly between a flange face and a locking nut. The ID of the ring is larger than the OD of a slotted flange stud for creating an annular space about the stud communicating with the slot in the flange stud. The annular space is closed at one end by the lock nut face. The other end of the annular space communicates with the space between the flange stud apertures and the screw teeth of the slotted stud. A radial opening or aperture through the injection ring communicates with the inner periphery of the ring and the annular space for permitting injection of a suitable sealant through the slotted stud into the flange joint.
