Abstract
A molded hopper tee for a hopper truck, tank trailer or the like is disclosed as having a first generally vertically directed hollow pipe section including a laterally outwardly directed flange at an upper end thereof for attachment to the bottom of a hopper and a second hollow pipe section extending generally transversely to the first hollow pipe section and extending beyond the first hollow pipe section on opposite sides thereof and terminating in opposite free ends for attachment to pipeline tubing at a discharge location. Bulk granular material particles can be pneumatically unloaded from the hopper and routed first through the vertically and horizontally directed hollow pipe sections, and then into the pipeline tubing. Opposite free ends of the second hollow pipe section include at least one circumferentially extending metal reinforcing element molded in-situ within and adjacent each free end. The laterally outwardly directed flange at the upper end of the first hollow pipe section also includes at least one metal reinforcing element molded in-situ so as to extend in the same direction as the laterally outwardly directed flange.
