Yes, but it's not rubber. It's the same material the 1pc SBC oil pan gasket is made of, so it won't harden, and blow out. It's embedded inside the plastic/fiberglass body the gasket is made of, and looks more like a raised edge than a round O-ring, so when it flattens out after being tightened it will seal flatter than a standard O-ring.
