After ordering two of these nozzles, I was able to get the original equipment nozzle cleaned out with some acetone and it has worked well ever since. So I have not used the new nozzles but have them if I need them. They are longer than the original ones so I will have to reset the z setting before using them. They also require a different size wrench.

I didn't know that a nozzle is considered a consumable on a 3D printer, and I would like to have known that before starting with this hobby.
I have since learned that hardened steel nozzles, ruby-tipped nozzles, and other options are available for other printers, and those have to be replaced much less frequently due to not being worn away from the inside simply by passing the filament through for printing.
There are abrasive filaments, but even bog-standard PLA will increase the internal diameter of the nozzle over time, which is why nozzles should be advertised as consumables.
Prints come out much cleaner with a new nozzle, but it isn't made clear that certain quality problems can be solved simply by replacing the nozzle.

Exactly what I needed. Perfect for my Delta Mini. Quick delivery. Very pleased.
