Vulcan Hart 00-418051-00057 Range Open Top Burner Orifice

The Vulcan Hart 00-418051-00057 Range Open Top Burner Orifice is a gas metering component used within compatible commercial range burner assemblies. Its #57 orifice opening controls the volume of gas entering the burner before combustion.

The orifice works with the surrounding gas train and burner components to maintain the specified fuel flow during operation.
