Where would you use a Schrader valve?

Are there different length Schrader valves?
No change in size – it’s an international standard. It’s possible that some Schrader valve stems have a thicker coat of rubber on them and maybe that is what is preventing your pump from going all the way on, but it is not the diameter of the threaded section.
