Abstract: A telescoping dip tube assembly having a first tube which telescopes within a second tube. The exterior surface of the first tube has a first tube stop ring extending outwardly from its exterior surface adjacent its bottom end. The second tube has a second tube stop ring which extends inwardly from its interior surface. When the second tube is lowered over the first tube, the bottom surface of the second tube stop ring engages the top surface of the first tube stop ring, thereby preventing the second tube from separating from the first tube. This arrangement provides the advantage of a telescoping dip tube assembly that is strong and durable and prevents the second tube from falling into a tanker while being loaded.
