(RK412) 12 inches tall. Perfect for 1 gallon size jugs. Made of clear rigid plastic. Has a curve on the top end to eliminate any problems with crimping hoses. The tube is closed on the bottom by a cap that diverts the suction away from the bottom. This helps to eliminate drawing any sediment while siphoning. Our 3/8 inch vinyl hose can be attached to the top end for easy siphoning.
