The present invention provides a gasket for use in a service portion of a brake control valve in a railway braking system. The gasket comprises an elastomeric composition with a predetermined shape. There is a series of bead-like projections formed on the first surface of the gasket for sealing such gasket with a body portion of the valve. A first aperture is disposed in the gasket at a predetermined location for engagement with a projection on the filling piece of the service portion. A brass insert is molded into the elastomeric composition and has a second aperture formed therein. The second aperture is in fluid communication with an auxiliary reservoir of such railway braking system. A third aperture is formed in the gasket in a third predetermined location. A brass insert, which has a first predetermined configuration, is molded into the elastomeric composition of the gasket. The brass insert is disposed in a lower quadrant of the first surface of the gasket and has a fourth aperture disposed therein having a second predetermined configuration. The fourth aperture is in fluid communication with a brake pipe. There are bead like projections formed on the opposed planar second surface of the gasket that correspond to similar positions, but radially opposed, for each of the bead like projections formed on the first surface of the gasket. The bead like projections formed on second surface are for sealing contact with such filling piece of such service portion.
