HIFLOW® Liquid flux is a specially formulated flux for brazing applications using a DISPENSER ( Fig:1), flux introduced into oxy-acetylene or liquefied petroleum gas-lines supplying flame through the brazing torch. 

HIFLOW® liquid flux is used almost exclusively in Torch Brazing. The fuel gas is passed through a Dispenser containing liquid flux. Liquid Flux is mixed in the fuel gas and comes out with the torch flame. The flux is applied by the flame where needed on base metals such as carbon steels, low alloy steels, cast iron, copper and copper alloys, nickel and nickel alloys, and precious metals.
