ABSTRACT:
An improved outlet tube (60) is provided for an air filter (10) of the type including a housing (12) having distally opposite axial ends (14 and 16), and a cylindrical filter element (34) in the housing (12), the cylindrical filter element (34) having an annular sidewall (40) with a hollow interior (58) and extending between distally opposite axial ends (48 and 50), wherein air flows radially inwardly through the annular sidewall (40) into the hollow interior (58) and then axially through the hollow interior (58). The outlet tube (60) is mounted to the axial end (14) of the housing (12) in snap-in relation and is rotatable relative thereto about the axis (62) of the cylindrical filter element (34) and communicates with the hollow interior (58) of the cylindrical filter element (34) for exhausting clean filtered air therefrom (64, 66). A seal (70) provides both axial and radial sealing of the outlet tube (60) to the housing (12), and seals the housing/outlet tube joint and allows the filter element (34) to seal both radially and axially with the housing/outlet tube assembly.
