The Orbit 1/2-in. Male-Threaded Brass Impact Head lets you replace or add an impact head to your yard’s watering system. Designed for dependability, impact heads have an uninterrupted water flow and are clog-resistant, even when used with dirty or reclaimed water from ponds and canals. Sprays up to a 90-ft. diameter; making it ideal for large-area watering. Easily adjust the coverage from a partial section to a full circle. Features a deflector shield for distance adjustment and an anti-backsplash arm to aid in spray pattern and area coverage. A simple twist of the diffuser screw breaks up the water stream, creating larger or smaller water droplets. The all-metal construction means it will hold up against the typical wear and tear that most impact sprinklers experience, giving you years of dependable use.
