APPARATUS FOR SEALING FLANGE JOINTS Abstract of the Disclosure 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 com- municating with the slot in the flange stud. The annular space is closed at one end by the lock nut fa?e. The other end of the annular space communi- cates with the space between the flange stud aper- tures 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 in- to the flange joint.
