We carry 3 sizes. 3/32" is recommended for general etching.
1/16" nozzles are for stage carving; it provides a smaller
(tighter)media pattern for smaller areas of etching
3/32" are standard; Rayzist determined them to be "the
standard" years ago when we first began to make equipment,
the sand pattern was not too small or to large.
1/8" are primarily used when blasting larger open areas,
such as signage or monuments (although we still use 3/32")
the orifice is larger so more sand and air dispenses from
the nozzle, giving a wider pattern of media, (the mixing valves
usually requires re-adjustment)
