Abstract
A gasket for railroad car manways or hatches is mounted on the top of a loading nozzle. The gasket is a ring having an inverted J-shaped cross section. It is held in position by a long down leg and a short leg. The legs are joined by a bail. The junction between the outside surfaces of the bail and down leg has a chamfer to avoid interference with a closed manway cover. Chevrons are formed on the upper surface of the bail. A flexible loop engages a bolt bracket on the loading nozzle to prevent dislodging of the gasket during opening of the cover.
