A wellscreen has a gravel pack assembly installed that can communicate slurry from a transport tube to a pack tube. A bypass has erosion resistant surfaces exposed to flow of the conveyed slurry and diverts portion of the conveyed slurry from the fluid bore of the transport tube to a tube opening, from which the pack tube extends. The bypass can be incorporated into the top ring for supporting the filter on the basepipes. A sheath of erosion resistance can be formed on or installed in a channel of the end ring to be covered by a cover.
