Abstract: A wall penetration sleeve for extending a conduit or pipe through a solid concrete, brick or other wall or connecting a first pipe provided on one side of the wall with a second pipe provided on the opposite side of the wall. The wall penetration sleeve is characterized by a cylindrical sleeve extending through the wall and internally threaded on each end to receive a corresponding pressure nut. Each pressure nut seals an o-ring or gasket in the corresponding end of the sleeve to form a moisture-tight seal between the sleeve interior and the interior of the wall such that liquid or gas cannot leak from the sleeve and accumulate in the interior of the wall as the liquid or gas flows through the pipe. An annular lock collar is either eccentrically mounted on the sleeve or includes a flat segment shaped in the collar edge to prevent the sleeve from rotating or moving transversely in the wall.
