This micro Bunsen burner is designed for use with LPG (liquid petroleum gas), butane, or other mixed gases with a heat value from 800 to 1200 BTU. It features a nickel-plated die-cast zinc alloy base, an aluminum mixing tube, a flame-stabilizing burner tip, and adjustable air ports. A serrated inlet arm accepts 6-8mm tubing for gas supply connection. Air supply is controlled by a nickel-plated brass sleeve covering ports at the lower end of the mixing tube, while gas flow is regulated by a needle valve fitted above the base for precise flame adjustment. The burner measures 3.75 inches in height with a base diameter of 3 inches.
