DCFirst Claim
1. A fitting for directing fluid flow through a preformed opening in a fluid impervious wall, said fitting comprising conduit means for receiving and directing fluid flow, having an inlet portion conforming in dimension with said preformed opening and retainer means for engaging and retaining said conduit means against the wall in communication with said preformed opening, said retainer means having a fluid passageway formed therethrough in communication with said conduit means for directing fluid flow therethrough, said passageway being formed with walls having at least one protrusion formed thereon and projecting a predetermined distance into said passageway for acquisition by a retention tool during fabrication and installation, without significantly impeding fluid flow through said fitting.

9. A fitting for directing fluid flow through a fluid impervious wall, said fitting being for fitment to a preformed opening in the wall, said fitting comprising:
-
a conduit member for fluid flow therethrough having an input end and an output end, said input end having an inlet portion conforming in dimension with the preformed opening and an annular flange disposed thereat for abutment against a first wall surface adjacent and in registry with the preformed opening, said input end having threads formed on the inner surface thereof; a retaining member for holding said conduit in fluid impervious contact with the first wall surface, said retaining member having a body portion with a fluid passageway formed therethrough and an annular flange projecting radially outwardly from one end of said body portion for abutment with a second wall surface adjacent the preformed opening, said body portion having threads formed on the outer surface thereof, said threads being configured to mate with said threads formed on said conduit, said body portion being configured for fitment through the preformed opening with said retaining member threads engaged with said conduit threads and said conduit flange in abutment with the first wall surface and said retaining member flange in abutment with the second wall surface to form a fluid impervious seal at the preformed opening for passage of fluid through said conduit. - View Dependent Claims (10, 11, 12, 13, 14)
