Heavy-duty and built to last in any irrigation system, HSJs are available in a multitude of the inlet, outlet, size, and length configurations with one perfect for every preference. Pair them one-for-one with any Hunter golf rotor purchase, and golf rotor warranties are extended from three to five years. These swing joints work extremely well with our commercial line of I-Series rotors as well. The following topics are discussed in the article below:
The swing joint provides 360° movement in all fittings to allow the correct installation height and vertical positioning of the rotor. These have O-ring threaded joints pre-assembled from the factory. The joints are pre-lubricated and should not be disassembled prior to installation.
For correct operation, the sealing is key for top performance. There should be about one or two threads showing, leaving about 4-5 threads engaged inside. The O-ring would be in the middle of the thread sealing area. From this point, the swing joint can be raised, lowered, or moved side-to-side very easily. After initial installation, heads can be raised, reset, then repacked at the correct height.
To properly use these swivels, we highly recommend the following prior to installation:
IMPORTANT: It is not recommended disassembling any of the joints in the field as the O-ring may get dirty creating a bad seal.
