Weber 64607 Genesis 425 & 435 (2022+) Natural Gas Manifold

What Problem This Part Solves

The manifold assembly distributes gas from the natural gas supply line to each burner valve. If the manifold becomes clogged, corroded, or damaged, the grill may experience uneven flames, poor burner performance, or gas leaks. Replacing the manifold restores proper gas flow, consistent heat distribution, and safe grill operation.
