The Komet Precision Twister (KPT) sprinkler is designed for use with a flexible hose drop or a semi-rigid polyethylene drop system. When using a semi-rigid poly drop, at least one steel adapter must be installed on the gooseneck side to ensure proper support and performance. The polyethylene pipe used for the drop should be of low- to medium-density material, providing the flexibility and durability required for reliable operation in irrigation applications.
