Transfers liquid using jiggle action. Continuous up and down movement “jiggling” sucks fluid up through the head and past a one-way valve into the hose, and gravity takes care of the rest. The hose is manufactured from an anti-static PVC material which is safe to use with most fluids including petrol, diesel, bio-fuels, anti-freeze, brake fluid and water, making this suitable for a wide range of uses, from draining fuel tanks to fish tanks.
