Bosch 00189321 Range Cooktop Venturi Burner Tube

Range Cooktop Venturi Burner Tube – Bosch

The cooktop venturi burner tube mixes air with gas in the correct ratio before delivering the mixture to the burner head for combustion. When the venturi tube is clogged, cracked, or damaged, the air-to-gas ratio is disrupted, resulting in weak, uneven, or yellow flames instead of a strong, steady blue flame. This direct-replacement venturi tube restores correct air-gas mixing and proper burner performance.
