A spiral wound gasket able to compress and seal under very low loads and provide sealing capabilities. The gasket generally includes a spiral wound metal portion and an outer guide ring to limit the compression of the gasket. For improved sealing capabilities a flexible graphite material is molded, extruded or layered onto the opposing faces of the gasket. In one embodiment, the graphite material is applied to substantially all of the gasket. In another embodiment, graphite sheets are applied to the outer guide ring while extruded graphite is applied to the outer surfaces of the metal winding. The spiral wound gasket provides a more durable gasket with low sealing load requirements and elimination of buckling under sealing loads.
