The PGP-ADJ, PGP-ULTRA, PGJ, and SRM Rotors are compatible with many types of nozzles to optimize watering in various landscapes. Each model uses specific nozzles and they are not interchangeable. Using an incorrect nozzle is the most common reason that a nozzle does not correctly fit inside the rotor. Please reference the images and notes below to verify you are using the correct nozzle for each of these models.
