An eduction tube assembly made of ultra high molecular weight polyethylene material for use on a containment vessel for corrosive liquids. It includes a vertical eduction tube and a unitary transition flange member having a first flange for connection of the assembly to an attachment flange associated with the vessel and a second flange to receive a connected hose flange. A single segmented ring with multi-directional capability is disposed between the flanges and receives securement elements to accomplish both connections. Bolts are used for one connection, upstanding threaded studs secured to the segmented ring are used for the other.
