A railcar comprises a hopper coupled to a discharge assembly. The discharge assembly comprises a discharge gate, a sloped side sheet, a gasket bracket, and a seal gasket. The sloped side sheet longitudinally extends above the discharge gate when the discharge gate is closed. The gasket bracket coupled to the sloped side sheet. The gasket bracket extends longitudinally along a bottom end of the sloped side sheet. The seal gasket is positioned between the sloped side sheet and the gasket bracket. The seal gasket has a straight section and a rounded section, such that a portion of the round section of the seal gasket is left beyond the bottom end of the sloped side sheet. The seal gasket creates a seal between the sloped side sheet and the discharge gate such that the weight of a lading increases the seal.
