Affordable alternative to the expensive ceramic gas burners.This listing is only for the burner with gas jet instaled. In order to work you will need gas hose with 5mm inner diameter, and also gas regulator valve for your own gas tank. Gas jet nozzle is 0.2mm, you can easily screw it in or out inside venturi, to set the right air-fuel mixture, after that you just lock it with locking nut on the top of venturi.
The black venturi handle is made from Teflon with 25% Graphite and able to withstand very high temperatures.Two side holes should newer be covered, they serve to supply the burner with air!
