The long air stem chrome is about 7″ in length. Because it is made of chrome, it is more durable and will not rust like the steel air stems. We also have a shorter air stem made of chrome that is about 5″ in length.
The air stem is part of the nozzle assembly, both finished and browning, though our nozzle assemblies come standard with the steel air stems unless otherwise requested. The air stem screws into the nozzle head.
Large hole is standard for our air stems, but small holes are available upon request.
