Do you use Teflon tape on sink supply lines?

You don't need to connect the faucets to the water supply lines if they have hot and cold lines. Teflon tape can be used to seal and lubricate threaded pipe joints.Most taps will have hot and cold water tubes, so just tie them to the appropriate water tube. It may be necessary to use the teflon band (a.k.a. fan band) for this part, which is used to seal and lubricate joints of threaded pipes.
