Yes, if you know the model of the existing manufacturer's sprinkler, you can use our Replacement Charts to find the appropriate Hunter pop-up or rotor that will have a similar flow and distance range. Hunter has rotors and sprinklers to fit all applications.
Hunter rotors have replaceable riser seals that may wear out over time. Sandy soils, sunken heads, or extremely hot and cold temperatures may also cause a seal to wear out prematurely.The riser seal is available as a single replacement part (P/N 181500) or replacement kit which includes 10 seals (P/N 253400).
Production of the G-Type rotor was discontinued 14 years ago, though many are still in use today. If a G-Type rotor needs to be replaced, the PGP-ADJ or PGP-Ultra is the current equivalent replacement.
The Hunter adjustment wrench consists of a 3/32 allen key, two convenient finger loops for gripping and an opposite side arc adjustment key for all your Hunter rotor adjustments. The Hunter wrench can be purchased from your local distributor. You can also use a 3/32 allen key for radius adjustment only.
