- said conduit member comprising;
(a) a substantially rigid tubular member having;
an inner surface defining an internal passageway;
an outer surface; and
, a connector end portion; and
,(b) a plurality of spaced annular ribs oriented on said tubular member outer surface;
each of said ribs being spaced between about 0.125 inches and 0.5 inches from the next adjacent rib;
each of said ribs having a sharply defined central ridge.

Abstract
An air flow conduit system is presented for air flow communication between an air filter mechanism and an engine intake manifold. The conduit system comprises first, second and third substantially rigid conduit members. Engagement between conduit members is provided by a rib system on a narrow end of a conduit member being received within a broad end of a next adjacent conduit member. Sealing engagement occurs by an elastomeric seal member positioned between the ribs and an end of a conduit member within which the ribs are received. A preferred rib arrangement is provided, to insure a flexible, multi-point, seal system.

10. An engagement arrangement for providing engagement between first and second conduit segments of a conduit system;
- said engagement arrangement comprising;
(a) a member having;
an internal surface defining an inner tubular passageway having a central longitudinal axis; and
, an outer surface with a connector end and with a plurality of spaced annular ribs thereon, each of said ribs having a forward side and a rearward side defining a central ridge therebetween;(i) said rib forward sides generally each facing away from said member outer surface connector end, and each projecting outwardly from said tubular member outer surface at a first obtuse angle of between about 95° and
about 115°
with respect to said first longitudinal axis;(ii) said rearward sides each facing generally oppositely from said forward facing sides and projecting outwardly from said tubular member outer surface and a second obtuse angle of between about 120° and
about 130°
with respect to said longitudinal axis(b) whereby sealing engagement between first and second conduit segments of a conduit system is facilitated by orienting said plurality of said spaced annular ribs therebetween.
