Pressure and heat molded polymer tube with interlocking grommet

An air filtering system comprising:

• a filtration tube;
• a cylindrical wall of the filtration tube, the cylindrical wall having a length with a top end and an opposite bottom end;
• a flange integral with the top end of the cylindrical wall and the filtration tube, the flange projecting outwardly from the top end of the cylindrical wall;
• a grommet, the grommet being formed as a cylindrical member with a cylindrical configuration, the grommet having an upper portion;
• a boss extending diametrically outward from the upper portion of the grommet and extending around the cylindrical configuration of the grommet;
• a groove in an interior of the boss, the groove being configured for insertion of the flange of the filtration tube into the groove when the filtration tube is inserted through the grommet, the groove being configured for locating the top end of the cylindrical wall of the filtration tube in the groove and locking the flange in position in the groove.

• a boss extending diametrically outward from the upper portion of the grommet and extending around the cylindrical configuration of the grommet, the boss being diametrically wider than an aperture through a transverse plate in a filter housing of the air filtering system;
• a groove in the interior surface of the grommet and in an interior of the boss, the groove having an annular shape that is configured for receiving the top end of the filtration tube in the annular shape of the groove in response to the filtration tube being inserted through the cylindrical configuration of the interior surface of the grommet, the groove being configured to receive the top end of the filtration tube in the groove and lock the top end of the filtration tube in position in the groove.
