For a number of applications it is easier to use a suction tube than a suction hose. Kin Pumps has a special suction tube for Ad Blue, which is fitted with a special coupling so that it fits the drums in which Ad Blue is supplied.

A suction tube is also used for rainwater reuse. Suction tubes are used to ensure that the submersible pumps for rainwater reuse can suck up the liquid at the right height so that as little pollution as possible is pumped.
