Abstract
A peripheral sealing gasket is disclosed for use in mounting a discharge gate to the adapter frame of a railroad hopper car. The gasket has a peripheral base formed of a relatively rigid sealing material, which base is formed and adapted to be positioned between and in substantial surface contact with a discharge gate mounting flange and the hopper car adapter frame. The base has at least one sealing element on each side thereof, which sealing elements extend outwardly beyond the base and are formed of a sealing material substantially less rigid than the base. There is a recess for each sealing element whereby each sealing element will distort into its recess during use so that the base is in substantial surface contact with the mounting flange and adapter frame throughout its peripheral extent.
