RTV on NG black pipe

Has anyone ever used Blue RTV silicone on NG black pipe or other gas fittings?. I know it's not for use with gasoline.
What about Permatex®, Form-A-Gasket® products or MotoSeal® #29132 that are designed for applications in a gasoline environment.

Thanks

    No. Wrong application. If you can't use it on gasoline it shouldn't be used on fuel oil or natural gas. They all come out of the same well.

    Exactly as @EBEBRATT-Ed said. There are specific products made for the petroleum industry to seal threads. Gasoila from Federal Process is my go to.

    I'm confused. What does methane have to do with gasoline and since when do they come out of the same well?


    I agree with j a. I don't know if it'll work but I doubt code allows it. Why do you ask? Damaged threads?

    Gasoline is refined from crude oil. Pockets of methane are frequently found while drilling and it’s effectively a byproduct. Modern techniques of extraction including “fracking” result in even more natural gas. That’s why it’s remained so cheap. Methane is a petroleum product. It’s a hydrocarbon. But it has a high ratio of hydrogen so it burns cleaner but much lower energy density so less portable.

    Refiners originally just burned it off then realized it could be cleaned, moisture removed and sold in pipelines direct to consumers like electricity. Cleaner than coal gas.

    Everyone seems to agree that dope is a lubricant and not a sealer.
    Just wanted to know if there was a sealer for gas pipe that would all most guarantee no leaks.

    Bury the threads, then a turn for luck? I've had to come along after him before!

    I certainly don't agree with that. Dope is both a sealer and a lubricant. In my opinion dope is a better lubricant and ptfe tape is a better sealer and combined they work better than one alone. But I've never used anything more than just dope on gas lines. It's such low pressure it's easy to seal.

    Thanks to all. Was always having a Pro do the gas. Was just going to make a suggestion if something turned up here.

    I was told by an Uponor Rep on a CSST fitting that was leaking no matter how much I tried to seal it to use Lock-n-Seal or Locktite to seal it. It worked.
