Drain assembly for a housing of a filter assembly

A drain assembly for a housing of a filter assembly, the drain assembly comprising:

• a drain body defining an elongated passageway along a central axis of the drain body, the drain body having:
• a first portion disposed about the central axis and configured to couple with the housing, and
• a second portion extending away from the first portion, the second portion having an outer circumference disposed about the central axis and a plurality of protrusions extending laterally away from the outer circumference;
• a retaining cap coupled to the second portion of the drain body, the retaining cap having:
• an inner wall defining a plurality of intermittently spaced resilient fingers disposed about the central axis, the plurality of resilient fingers having ends extending laterally towards the central axis for capturing therebetween the plurality of protrusions located on the outer circumference of the second portion of the drain body, and
• an outer wall disposed about the inner wall and located in a spaced-apart relation to the inner wall, the outer wall defining a plurality of apertures disposed laterally with respect to the central axis;
• a hose barb body rotatably disposed about the central axis, the hose barb body having:
• a tapered portion configured to receive the second end of the drain body, the tapered portion defining a lip at an end thereof, the lip disposed proximal to the ends of the resilient fingers of the retaining cap, and
• a cylindrical portion extending from the tapered portion, the cylindrical portion having an outer circumference configured to allow selective coupling of a hose thereon;
• and
• a retaining collar disposed about the central axis, the retaining collar having:
• a shoulder disposed proximal to an underside of the lip of the hose barb body, the shoulder configured to bear the hose barb body thereon, and
• a plurality of resilient tabs upstanding from the shoulder, the plurality of resilient tabs having ends laterally extending away from the central axis for engaging with the plurality of apertures defined in the outer wall of the retaining cap.
