Venturi Gas and Air Mixers

A venturi is used to mix gas and air before it goes to a burner.  Venturis are often used with a black drilled pipe or stainless steel pipe nipple (pipe burner) that is capped off or in a variety of special applications where the air and gas mixture is being sent to the burner. Burners can be a remote cast iron burner or a pipe burner. 

Our venturi has a 1 1/4" FNPT outlet for larger gas volumes, to be used usually with a 1 1/4" Inner Diameter Pipe.
It can be used with low or high gas pressure propane and natural gas depending on the orifice chosen.
