A check valve for a breather assembly includes a valve seat defining a seat opening, a valve stop coupled to the valve seat, and a valve element disposed between the valve seat and the valve stop and including a first element surface and a second element surface. The valve element may be sufficiently flexible to actuate between a closed position, in which the first element surface engages the valve seat, and an open position, in which the second element surface engages the valve stop. The valve element may further include a passage, such as apertures, extending from the first element surface to the second element surface.
