Many people have purchased waste oil nozzles on line only to discover they dont work as advertised . I have bin designing and testing waste oil burners and exotic Combustion system for industrial processes for 10 years  and you will be impressed with the different these nozzles can make to your industrial process. This burner is currently all over the world running factories for my customers doing things like drying grain and nuts , making fuel from tires and smelting metal  

My clients often tell me stories of having purchased china brand siphon nozzels only to discover they have bin deceived with both specifications and functionality. They also come to me after having bought a $1000 diesel/ waste oil burner that wont burn waste oil and puts out 1/4 of the rated power . We only provide the bracket in the pick for extra $15 , it comes with a very effective standard bracket
