The rubber protector is not sized properly and quite loose, but it does stay on. There are nicks and dents to the rim of the sprayer.
The spray was adjusted by hand, didn't need to use any tools. The same is true with disassembling it... It's tight but manageable by hand. Check out the identifications stamped into it; I couldn't read what is inside the triangle.
