Pilot Orifices
Anderson & Forrester Pilot Orifices
Pilot orifices work and operate just like burner orifices. The difference between the two is that pilot orifices have smaller holes to support a smaller flame.
Pilot orifices can be mounted like burner orifices (screwed into a threaded hole), but usually they are mounted using a compression or flare fitting.
Anderson & Forrester manufactures eight different kinds of pilot orifices, in a variety of sizes for your convenience. We also make corresponding orifice tips and pilot extensions to help make your job easier and more efficient.
At Anderson & Forrester, we carry pilot orifices and fittings from Penn-Baso, a leader in the industry. Penn-Baso pilot orifices come in kits and are sold separately for use in various applications.
