Toro 307-00 157° Arc Disc — Replacement Rotor Nozzle

The Toro 307-00 157° Arc Disc is an OEM replacement rotor nozzle designed to restore precise 157-degree coverage in compatible Toro stream rotor heads. This compact disc installs quickly and delivers the arc pattern needed for sector and partial-circle watering zones.

• Exact 157° arc: Provides consistent sector coverage for targeted watering.
• OEM compatibility: Made for Toro 340 series stream rotors and similar rotor modules; confirm SKU before ordering.
• Quick swap installation: Removes and installs without tools in most rotor housings for fast field service.
• Reliable spray pattern: Engineered to maintain even distribution and reduce overspray in partial arcs.
• Low-cost replacement: Economical spare part to keep zones running without replacing entire rotors.

Typical applications include irrigation of landscaped beds, lawn edges, and narrow zones where a partial-circle spray is required. Use with proper pressure ranges and matched nozzles for best efficiency. Keep spare discs on hand for seasonal maintenance and quick repairs.

Replacement is straightforward: rotate rotor head to service position, remove the old disc module, insert the Toro 307-00 until it seats, then return the rotor to service. Regular inspection and gentle cleaning extend service life and help maintain uniform coverage across the irrigation zone.

Before ordering, verify your rotor model and SKU (307-00) to ensure compatibility. For routine care, inspect ports for debris and replace discs that show wear or damage. Contact product support with part number for fit guidance.
