ptfe tape for gas
 

You can buy PTFE tape marked as suitable for gas. However, I was told by a corgi registered plumber that it should not be used for gas! They reckoned you should use gas jointing paste only. Any views on this?

What sort of gas?
Yes there are different grades of PTFE, inc. oil free for oxygen.

As far as nat. gas installs I would tend to use the paste as its
supposed to be non-hardening, so a joint that gets moved
ever-so-slightly remains sealed, PTFE after time will tend to set, any
movement=leak.
