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 assembly includes pressure hardware in sets each including a bolt, a matching nut, and a first molded resin pressure plate that has a recess large enough for the bolt head to seat in freely rotatable relation in it, with peripheral access for a wrench around the bolt head; a washer is rotatably positioned in the bottom of the recess, which is deep enough so that the bolt head does not project substantially out of the recess. The first pressure plate has a bolt-receiving aperture large enough to admit the bolt rod but small enough to block the bolt head. A second molded resin pressure plate has a socket complementary to the nut, so that the nut seats it in non-rotatable relation; the second pressure plate also has a bolt-receiving aperture to admit the distal end of the bolt rod into engagement with the nut.
