  • Designed for 300 Series rotors: Direct-fit #01 nozzle assembly for Toro 300 Series multi-stream rotors in high-pop bodies.
  • #01 coverage & radius: The #01 arc disc/nozzle delivers a coverage radius in the approximate 4.9–5.5 m range, suitable for small-to-medium lawn zones.
  • High-pop compatible: 3" (76 mm) high-pop configuration for installations where a higher spray elevation is required.
  • Includes necessary parts: Supplied as a nozzle assembly that includes the nozzle, cap plug and screw for straightforward replacement.
  • Durable construction: Stream rotor components combine engineered plastic and stainless-steel elements for corrosion resistance and season-long reliability.
  • Service & upgrade note: For older rotor systems, technicians commonly recommend upgrading to modern rotors such as Toro T5, Hunter PGOP, or Rain Bird 5004 for improved performance.

This Toro 300-21 #01 Nozzle Assembly provides a simple, cost-effective way to restore even coverage and reliable operation to 300 Series high-pop rotor heads. Install as a direct replacement in compatible high-pop bodies and check nozzle selection and operating pressure when adjusting radius or arc.
