The animal watering device includes a tubular housing (1) having a through-bore (2) divided into a valve portion (4) and an outlet portion (5). A valve mechanism in the valve portion includes a flexible tubular insert (17) through which the valve stem (11) at least partially extends. The valve stem is connected to a nipple (10) in the outlet portion, which is actuated by an animal to open the valve. The tubular insert includes the valve seat (16) and an integral skirt extending around the periphery of the valve plate (12). The insert rests against a shoulder (3) separating the valve portion from the outlet portion.
