Abstract
A rotatable head sprinkler apparatus incorporates a lower bearing seal between a swivel device for connection to a source of water under pressure, and a spindle connected through said swivel device to a self-powered rotary sprinkler head of the type used for irrigation. A bearing washer is formed into the swivel device and forms a coupling for a protective seal which prevents the entry of trash, or the like, into the area between the seal and the wear washer.
