Abstract

A polymeric hose assembly including a male hose inserted within a female hose connects an air cleaner to an internal combustion engine. An elastomeric seal including a plurality of bellows is bonded around the circumference of the exterior surfaces of the female hose and the male hose at bonding points. The plurality of bellows expand to allow for the expansion of the hose assembly to accommodate for engine movement and vibrations.
