Teflon tape on gas pipe??
I replaced my water heater yesterday and used a flexible gas pipe to
reconnect natural gas to it. I used my white Teflon tape on the fittings for a seal and all appears well. Then I noticed some info on the internet that you should not use white Teflon tape on gas fittings - only yellow. Apparently there is a risk [don't know how great] that the white tape can damage the gas regulator or such due to bits of it shredding off. Now I am wondering if I should change it or just leave it. My thinking is that removing/reinstalling the fittings may introduce more risk that just leaving well enough alone? The gas heater is installed in the basement next to the furnace right next to a floor drain. Any advice appreciated. --- Steve |

Seems the yellow is just thicker. http://www.cleanfit.com/tapes.htm |
In general, the yellow is thicker and higher density.
I would redo it. Aren't you going to feel silly if you have a problem because you didn't want to do 20 minutes work? |
I was taught to use white teflon, and also Rectorseal. The teflon allows the
threads to slip tighter, and the Rectorseal does the acutal sealing. -- Christopher A.

I would replace it with either the gas-rated tape, or the old-fashoined
gooey pipe sealer. The typical white teflon tape is not to code, or so I have been told by a plumber I happened to ask at the hardware store, who was most emphatic. |

Thanks for all the replies. All continues to work well and I verified that
the gas connections are leak free. I did some searching on the internet and could not find any evidence of more than usual premature failures of gas water heaters [gas delivery related] because of using white Teflon tape on the gas pipe connection. My guess is that there probably is some sort of inlet screen on the thermostat to stop large particles from getting into it. Also I feel that disassembling it at this point could do more harm than good due to all the Teflon tape that would come loose in the threads during the removal process. Thanks again and next time for sure I will use the yellow stuff. --- Steve "Steven L Umbach" wrote in message ...

Each of my downward pipes that is going into the heater or furnace as a T at the bottom with dead end let with a cap on it. I guess any thing that goes down that pipe ends up in this small dead in drop area. There are several of these. Is there any specific amouont of torque that should be on a gas pipe? -- Respectfully, CL Gilbert |

Interesting enough today the wife and I went shopping the local home
improvement chain stores [northwest Chicago] for light fixtures and I took a look at their flexible gas connection kits out of curiosity. Both chain stores included skinny WHITE Teflon tape spool with their kits for use with the gas connections.

As someone else mentioned, you shouldn't be using any type of thread
sealer on gas flex pipe. Those are flare connections and no gas should even be exposed to the threads. In fact, putting anything on the threads may make it harder to get the flare connection tight enough. You only seal rigid pipe-to-fitting connections. |

Yes there is and that's pipe dope. Faster and easier. I can do six threads with pipe dope in the time it takes to do one with tape. Besides, they make yellow tape for gas applications. I've only used pipe dope a couple times in the last 40 years. It's easier/cleaner to use tape and tape provides a better seal. BTW, were you "making" a joke there? If tape is so superior for leaks, odd that code still allows for pipe dope, draws no such distinction and plumbers widely use both. |

I bought a PTZ dome camera from China and they sent along the biggest roll of teflon tape I've ever seen. When I ordered a second one, it came with an O ring to provide the same waterproofing. I spent quite some time (as Tony warned I might) trying to find out more from the Chinese vendors to no avail. Oh well, the camera was 1/4 what US vendors wanted for the same thing that probably came with the same obtuse directions. Going to deploy one this weekend - not sure I should water test it with the garden hose before bothering to climb the ladder. Apparently water can get in through the wire entrance to the threaded dome cap. But I'd rather do it with tape because it might have to be taken down to dry out if the tape/gasketing doesn't work. I bought some (wildly overpriced) stuff called Sugru that is a hardening putty that I might use to seal the wire entry because it's fairly easy to remove. https://sugru.com/ (No affiliation and we'll find out tomorrow if it does what it says.) -- Bobby G. |

Removing a taped joint is the same as removing a dope joint, you just unscrew it. It doesn't require removing pipe dope. And if you're putting it back together and want to clean it up, either a rag or a wire brush works for me. Funny, if pipe dope is so hard to use, why do so many pros still use it? |

White PTFE is single thickness, yellow is double and pink is triple. I know of nowhere it is in any Code requirement and unless it's been changed which I think it hasn't, the National Fuel Gas Code handbook 2.6.7(d) refers to using pipe dope suitable for use with gas and says: "This requirements does not prohibit the use of teflon tape as a pipe dope.

Something about the gas dissolving the tape. It's ok on propane though. There is a special tape made for nat. gas, but I have never used it. so I dont know the name of it, or if it's readily available. Years ago, I did some work on nat. gas pipes, for my parents. I just used pipe dope. Where I live now, I only have propane, but I still use pipe dope. Normally people use copper tubing for propane, so no sealer is needed since the fittings are flared copper or compression rings. But my house had black iron pipe for the furnace. When I ran a line to the kitchen for a stove, I decided it was best to keep the same pipe to prevent dialectric corrosion, so I used black iron pipe with dope in the fittings. |

I'll confess to using teflon tape on the face of a POL fitting. sometimes you do what you gotta do to make the connection stop blowing bubbles. |
