摘要： A gasket for a steel coil railroad car wherein the gasket is contained within a U-shaped channel in the coil cover. The gasket includes a base which has a mediate section which joins opposite flanges and a bulbous portion which defines a volume. The bulbous portion has a mediate flat section that joins opposite arcuate sections. The mediate section of the base is thicker than the arcuate sections and the flat section of the bulbous portion. The gasket is retained in the U-shaped channel in such a fashion that the base contacts the mediate portion of the U-shaped channel. The gasket is compressible upon the engagement of the gasket with the railroad car so as to form a seal between the coil cover and the railroad car.
