In connections that do use tape, like old galvanized steel pipe, the tape is entirely within the joints, because it's a lubricant.

- kube-system 4y agoYeah, there is generally no PTFE in the middle of anyone's PEX or copper system. Thread sealant only goes on threads, and PEX systems are crimped together and copper systems are (generally) soldered together. Threaded fittings are expensive and so they're avoided when possible. But, either system will have often have PTFE at any terminations where transitioning to other fixtures via threaded fittings.
