I have a sandblasting gun like this:

I have a couple of boxes of nozzles for it, that happen to fit
perfectly. They are hardened steel nozzles.

My question is, how many hours of blasting do these nozzles last? I
want to understand how many do I need and maybe I can sell the excess,
as they seem to be selling for $18 each at McMaster-Carr.

Keep 'em . You'll use them eventually , and if you sell these you'll be
buying them back for more later .


I have like 100 of them. But, I guess you are right, cannot have too
many.

From what I have read, steel nozzles are eaten up much more quickly
than ceramic, so your stock isn't that long-lived, Ig.

True indeed. My gun has Carbide lined nozzles..and even they wear down
over 5-6 yrs with my usage
