ABSTRACT:
An improved outlet gate pan gasket is located between the outlet gate and outlet flange of a hopper car. The gasket includes a central web which fits around the perimeter of the outlet aperture. An inner margin is attached to the inner periphery of the web and an outer margin is attached to the outer periphery. The inner margin has upper and lower horizontal surfaces joined by an edge surface which is perpendicular to the horizontal surfaces prior to compression of the gasket between the gate and outlet flanges. The inner margin has a solid cross-section. The uncompressed thickness of the inner margin is greater than that of either the web or outer margin.
