摘要： An endcap including a first plate member including a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions of the first plate member and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal includes a first portion thereof engaged with an axial facing surface of the first plate member and a second portion thereof engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion thereof axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction.
