Hello, there! We appreciate your interest in our Rainbird 12HC1 Half Circle Sprinkler Nozzle. Page 11 of this catalog says that the 12HC1 nozzle is compatible with all Rain Bird Pop-up sprinklers. Sorry, but Toro is a different brand, so this Rainbird 12HC1 nozzle is not compatible with your Toro sprinkler. Thank you for trusting PlumbersStock.com. Have a great day!
