MP Rotator - Installation

Hunter MP Rotators fit on a traditional pop-up or fixed spray body. The most common bodies are the female threaded version. MP Rotators are also available in a male thread version if needed. MP Rotators make a great replacement for spray nozzles adding the benefit of being a much more efficient nozzle with low precipitation and matched uniformity.
