Do you use plumbers grease inside of faucets?

I'm replacing the steel ball located inside a single handle tub faucet. I noticed some people use plumber grease to lubricate the ball and rubber seats. One brand I was looking at says not to use the grease on o rings or rubber parts. Should I use plumbers grease for my application? If so, what type or brand should I use?

It looks like silicone grease is what is recommended. Is it necessary to apply in my application?

Many of the parts come from the factory with some silicon based plumber's grease on them. While maybe not required, in my limited experience, it makes things smoother to operate. Can't say if they actually last longer. You do not want to use any petroleum based grease or other product on the rubber - first, because when you use hot water some of it could dissolve, and second, some rubbers will be damaged because of it.

My tiny cup of plumber's grease is MANY years old because I SELDOM use it on faucets of any kind.
