Question Installing a faucet. Where do I need thread tape?

I'm putting a faucet back in after installing new kitchen cabinets. I noticed none of the treaded connections had thread tape on them from when originally installed. Should i use it or not. My thinking is "it can't hurt". But those are often famous last words.

Also, the rubber seals under the faucet where it goes thorough the counter top are pretty dried out. Can I just use plumbers putty to seal them?

Plumbers putty is an acceptable seal. Sometimes silicone is used in the case of a stone countertop.
Plumbers putty has oils in it that can leach into lightly colored stone.

Most faucet connections don't require tape but if yours had it on then it may have been needed. Hard to answer without knowing the exact type of connection.

Like Pete said, the connections from the faucet to the angle stop does not require thread tape. Because of the rubber washer inside, tape can actually make the connection leak.
