Oval pipe and fittings are primarily used for air distribution runs in interior walls to convey conditioned air to upper stories.  The slim profile allows for use in standard stud wall cavities and in joist spaces between floors.  The nominal size of oval has a cross sectioned area that is less than that of the corresponding size of pipe.  Review both of these charts to make sure of correct sizing.  Typical application; round takeoff to round pipe from duct.  The round pipe makes a transition to oval by using a 859.  Oval pipe is attached to the other side of the 859 and continues up between the stud spaces in an interior wall to the second floor.
