A seal for an axle assembly can include a support, sealant layer, lip, and flange. The support can include an outer member and a wall. The outer member can extend axially. The wall can extend radially inward from a first end of the outer member. The sealant layer can coat an outer surface of the outer member to form a fluid-tight seal between the outer surface of the outer member and a bore of the housing. The lip can extend radially inward of the wall. The lip can form a fluid-tight seal between the wall and an outer surface of the shaft. The flange can extend radially outward of a first end of the outer member while not forming a fluid-tight seal with the interior bore. The flange and the outer member can define a channel axially between the first end of the outer member and the sealant layer.
