The Hevan series nozzles combine water saving performance with the convenience and versatility of variable arc nozzles. They can replace the nozzles on most major brands of spray heads. The nozzles' superior flow control technology delivers more uniform spray coverage across the pattern, even close to the head. Producing larger droplets that fall quickly and resist wind-blown overspray, Hevan nozzles also help you keep water on the grass, not on the sidewalk, driveway or buildings. With a simple twist of the nozzle collar you can adjust the spray pattern from 0 degree to 360 degrees.
