The ultimate in reliability for a long suction hose, this kit is supplied completely assembled so that you can use it straight out of the box. The 20m length of 50mm blue "Nitrile" suction hose has a white hard PVC helix inside to maintain its round shape even under maximum suction, fitted with a Hansen 50mm foot valve, Norma all stainless steel clamps and heavy duty aluminium camlock fittings for instant secure connection to the inlet of your pump. This unit is designed for use with any brand of fire fighting style pump that has a 2" male BSP inlet. If your pump has the 1 1/2" inlet, we can supply a bush so that it still fits perfectly. Note, the image shows a length of hose 20m.
