ABSTRACT:
A vortex air precleaner having snap-fit, self-sealing vortex tubes. Each vortex tube includes a flexible lip projecting laterally outward from the tube and spaced from an end of the tube. An annular shoulder is located between the lip and the tube end and spaced from the lip to provide a groove therebetween. The portion of the tube extending from the shoulder to the tube end is tapered inwardly and is formed with a plurality of longitudinal slits to provide the tube end portion with radial flexibility. When the tube end is inserted within an opening in the wall of the precleaner, the end portion will flex inwardly enabling the precleaner wall to be engaged with the groove, and the flexible lip engages the surface of the precleaner wall to provide a tight sealed joint.
