a condulet sized to receive a rigid or intermediate metal conduit of the metal conduit raceway the condulet formed integrally as one piece, the condulet comprising:

a condulet body; and a mouth comprising: a mouth wall extending from the condulet body; and

an interior ridge positioned circumferentially along an interior of the mouth wall and extending from the interior of the mouth wall, the interior ridge formed integrally with the mouth wall, the interior ridge including a plurality of projections and a plurality of recesses and having a wavy outline with the plurality of projections forming a plurality of convex portions of the outline and the plurality of recesses forming a plurality of concave portions of the outline, the plurality of projections configured to form a plurality of indentations circumferentially around an exterior of the metal conduit and engage the metal conduit at the plurality of indentations when the mouth is compressed with the metal conduit received therein; and

a gasket sized to circumscribe the metal conduit and comprising: a ring body forming at least part of a circle and having a first side and a second side opposite the first side, the first side facing a center of the circle; and a first lip positioned on the first side and extending circumferentially along the ring body, wherein the gasket deforms and seals a gap between the interior of the mouth wall and the exterior of the metal conduit when the mouth is compressed with the metal conduit received therein.
