Mushybees. Gas PTFE tape is much thicker. Can be used on joints on water pipe work but its overkill IMO. Regular PTFE shouldnt be used on gas joints but you shouldnt be working on gas pipes if you dont know that.

Additionally, do you use Teflon tape on water supply lines? Most faucets will have hot and cold water supply lines attached, so you just need to connect them to the appropriate water supply line. You may need to use Teflon tape (aka plumbers tape) for this part, which is used to seal and lubricate threaded pipe joints.

Secondly, can you use yellow Teflon tape on water lines?

Teflon tape is less messy High-density pink tape is used on water lines; yellow tape is designed for gas-line use. White tape (often low density) is used on water lines.

Will plumbers tape fix a leak?

These type of leaks must be repaired by cutting the PVC pipe and replacing the fitting. If your pipe fitting is threaded at the place of the leak, you may very well be able to stop the drip by unscrewing the pipe joint and replacing the tape. Teflon tape will work on any of these threaded fittings.
