A suction hose is a flexible tube used to draw liquids, gases, or fine particles into a pump or vacuum system. It is typically made of durable materials such as PVC or rubber to withstand the suction pressure and prevent collapse during use. Suction hoses are commonly used in industries such as agriculture, construction, and firefighting to transfer water, chemicals, or debris. They come in various lengths and diameters to accommodate different applications and can be attached to pumps, filters, or other equipment to facilitate the transfer of fluids or materials.
