Abstract
A gasket for a hopper outlet is disclosed, particularly well-suited for use between the frame of the hopper and the frame of an unloading outlet for a railway hopper car. The gasket has a central metal frame carrying a pair of relatively hard, continuous elastomeric seals along each edge of the frame. Each of the seals has a lip which protrudes upwardly (or downwardly) and outwardly from the body of the gasket so as to be readily compressed upon initially mating with the frames to ensure sealing even if the frames are warped. Such a gasket may be retrofitted to existing outlets.
