Weber 70309 Summit 600 Series Main Corrugated Gas Line

What Problem This Part Solves

The main corrugated gas line safely transports fuel from the grill’s supply connection to the burner manifold. If the line becomes kinked, cracked, or damaged, it can restrict gas flow or create leaks, resulting in poor burner performance or unsafe operation. Replacing the gas line restores proper fuel delivery and helps maintain safe grill operation.
