Kanaline FW is a heavy-duty suction and discharge hose that is lightweight and flexible. The helical PVC allows for easy drag, while the see-through PVC allows you to visually inspect flow.
Hose sizes also correspond to the Tri Clamp size when purchased banded & clamped. I.e. 1.5" hose has 1.5" TC ends. 2" hose has 2" TC ends. Etc. To move up or down in size, use a Tri Clamp Reducer
