I want to install the following umbrella valve stem seals
As far as I understand they make o-rings obsolete. But some recommend using umbrella seals (I guess those with simpler design, i.e. without the spiral) together with o-rings on a valve. Any opinions on that?

BTW: I know positive valve stems seals might be the best solution. However, I had to rule them out in my case.
