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?

Any views on this? t60 I've heard of PTFE being used on copper compresion fittings, and joint paste on malleable iron fittings, so I think both are acceptable in their own ways. Joint paste is the way to go though, but only if you know you're applying it properly. |

PTFE for gas is acceptable for pipework upto 2" and can be used on pipework upto 4" if checked with manufacturer on lower pressure gas (21mb). We use it all the time on pipe upto 2" but then use hemp/paste on larger diameter pipework. Lee --- avast! Antivirus: Outbound message clean.

From what i have been told (before my time!!) it was ok to use, then banned, now ok to use again, has been for a few years now i think. Long screw.....sod that, use a union, much easier!! ;o) Lee --- avast! Antivirus: Outbound message clean.
