ABSTRACT:
Pressure hardware for a seal block assembly used to form a modular, annular seal around a conduit passing through a wall, the assembly including elastomer seal blocks joined in an annulus around the conduit, the seal blocks having pressure bolt apertures parallel to the conduit; the seal blocks are axially compressed and radially expanded to form the seal. The pressure hardware is in sets each including a bolt, a matching nut, and a first molded resin pressure plate having a recess large enough for freely rotatably seating the bolt head, with peripheral access for a wrench; a washer is rotatably positioned in the bottom of the recess, which is deep enough so that the bolt head does not project substantially. The bolt rod extends through a bolt-receiving aperture in the first pressure plate. A second molded resin pressure plate has a socket complementary to the nut, which seats in the socket non-rotatably relation and a bolt-receiving aperture allow the bolt rod to engage the nut; in one form, the socket has crush ribs to hold the nut firmly in place. In another embodiment, the second molded resin pressure plate has a threaded bolt-receiving aperture in which the bolt rod engages. Also disclosed are resin caps that inhibit corrosion of the metal parts of the assembly.
