Used to regulate gas flow within commercial cooking equipment, this hood orifice controls the precise amount of gas delivered to the burner by restricting flow through a calibrated #51 hole. Threaded with a 3/8"-27 connection, it is fitted onto the gas supply system where accurate fuel metering is required to maintain proper combustion characteristics. Built with precision for consistent gas distribution, the orifice plays a critical role in ensuring stable flame output, efficient heating performance, and safe operation in gas fryers, griddles, and ranges. Commonly applied in commercial kitchens and foodservice equipment, it helps maintain the correct air-to-gas ratio for reliable burner function. If an orifice becomes clogged, worn, or incorrectly sized, it can lead to uneven flames, poor heating consistency, or inefficient fuel usage; replacing it restores controlled gas flow and supports proper equipment performance.
