1. A filter assembly, comprising:
a port comprising an inner surface that defines an aperture extending through the port, the port including an upper portion comprising at least one surface modification that protrudes axially so as to define a top portion; and
a filter element comprising:
a filter media;
a top endplate and a bottom endplate positioned on opposite ends of the filter media; and
a filter element extension directly connected to one of the top endplate, the bottom endplate, or the filter media, the filter element extension including a seal member and an end portion, the seal member being attachable to the end portion of the filter element extension, the port and the filter element extension alignable and sealingly connectable with each other,
the inner surface of the port forming a seal with the seal member of the filter element extension when the port and the filter element extension are aligned such that the seal member seals within the aperture and the at least one surface modification of the port does not abut the seal member of the filter element extension, thereby creating a sealed connection between the port and the filter element extension wherein the at least one surface modification comprises at least one of a notch, protrusion, groove, cut, and surface roughness.
