A rubber flat gasket (also called a rubber washer) is a thin, disc-shaped rubber product widely used in industrial sealing applications. It is placed between two flat mating surfaces (e.g., metal flanges, bolts, etc.) and seals by deforming to fill microscopic gaps, providing functions such as sealing, leak prevention, anti-slip, vibration damping, and cushioning.

Unlike the "backup ring" discussed earlier, a flat gasket is typically used independently and does not rely on a primary seal like an O-ring.

Rubber flat gaskets can be manufactured from various materials to suit different operating conditions. Each material offers distinct performance advantages:
