Abstract: An adapter is provided for fluidly coupling a hose to a housing of a filter assembly having a drain body connected to the housing. The adapter has a retaining cap that is disposed about a central axis and is configured to couple with the drain body. A hose barb body is disposed rotatably about the central axis. The hose barb body has a tapered portion that is configured to receive at least a portion of the drain body therein, and a cylindrical portion that extends from the tapered portion. The cylindrical portion is configured to allow selective coupling of a hose thereon. A retaining collar is disposed about the central axis and has a shoulder that is configured to bear the hose barb body thereon. Multiple resilient tabs upstanding from the shoulder have ends laterally extending away from the central axis for engaging with the retaining cap.

Abstract: The present disclosure relates to a filter element for use in a fluid filter system is disclosed herein. The filter element comprises a filter medium having a longitudinal axis between a first end and a second end, and an end cap assembly attached to the first end of the filter medium. The end cap assembly includes a first end cap aligned with the longitudinal axis and proximate to the first end of the filter medium; a first member concentric with and disposed radially apart from the first end cap and the filter medium and axially between the first end cap and the second end of the filter medium; and a plurality of arms connecting the first end cap with the first member, each arm configured to align the filter element with respect to the container and base plate by absorbing alignment discrepancies between at least the base plate and container.
