ABSTRACT:
A fitting sealing an intersection of a pipe passing through a wall includes an adapter assembly including an elongated threaded sleeve with an enlarged flange at one end, an adapter gasket, an O-ring and its support, and a nut threadedly joined to the sleeve to squeeze the O-ring and gasket against opposite sides of the wall. The adapter assembly fits concentrically around the pipe where it passes through the wall; and two generally hemispherical resilient covers enclose the portions of the adapter assembly on each side of the wall. Hose clamps at each end of each hemispherical cover connects the enlarged end portions to the adapter assembly and the other end portions to the pipe. One of the hemispherical covers has a pressure grease fitting thereon to allow the space between the covers and the adapter assembly to be filled with pressurized water repellent gel.
