ABSTRACT:
A filter apparatus includes a filter housing having at least one opening and a plurality of retention tabs positioned proximate to at least one of the openings and secured to the filter housing. Also included is a connection fitting having a tube segment sized and configured to be received into at least one opening of the filter housing, orientation tab or tabs secured to the connection fitting and positioned to be engageable between a portion of the plurality of retention tabs when in the installed position. A retention flange extends radially from the tube segment and is configured to retentively engage with the retention tabs to secure the connection fitting to the filter housing. The connection fitting is rotatable when the tube segment is received into the filter housing but is then rotationally locked relative to the filter housing when in the installed position.
