Gas nozzles & injectors

Gas nozzles and injectors meter the fuel entering the burner head, controlling the flow rate and spray pattern that determines combustion quality. They sit at the point where the gas circuit meets the burner, and their geometry directly influences flame shape, heat output and emissions. Wear, partial blockage or an incorrect replacement will affect combustion efficiency and may trigger safety lockout.

Selecting the correct nozzle depends on orifice diameter, thread size and pitch, flow rating at the appliance's nominal inlet pressure, and spray angle. Connection type — whether a straight or angled body — matters for routing in confined burner assemblies. An order number from the original manufacturer can in most cases be cross-referenced to a compatible part in this catalogue; use the model designation or appliance serial prefix if the original reference is no longer listed.
