Wow... It is just dumb to put both on a pipe. Use one or the other. I saw a Youtube of putting pipe dope on a flaired fitting threads. Another dumb move as there should be nothing to leak at the threaded part. If it does leak, something was not done correctly. Correct. |

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. More polichromatic bovine excrement.. Natural gas and propane have the exact same effect on teflon tape - none at all. However, pipe dope mis recommended over tape because the tape can cut and turn into "threads" of teflon and block orifices or stick in valves. There are 3 basic teflon tapes - white(single thickness) , yellow (double thickness) and pionk (triple thickness. White is forbidden in all gas connections. Some places allow yellow - some allow pink, and some do not allow tape at all. I was told this about not using teflon tape back in the late 70's or early 80's. What I heard was pretty vague, and I dont recall who said it anymore. Anyhow, these days we have better access to information. Either way, I guess I was told correctly to NOT use it, but for the wrong reason. What you said makes a lot of sense. I am fully aware of using teflon tape on plumbing, and when I'd first turn on the water, the faucet strainers would clog. I'd remove them, and find rust particles (if ther was OLD steel pipe involved), -AND- pieces of teflon tape, along with little bits of solder (on copper pipe). On plbg its easy to remove, but I could see orfices and stuff getting quickly clogged on gas pipes. I'll just stick with using pipe dope on all gas pipes! My go to pipe joint sealant is,"Leak Lock" manufactured by Highside Chemicals. I keep a 1.3oz blue tube in my toolbag and it lasts for years. It seals everything but alcohol so don't use it on your moonshine still. ^_^ http://www.highsidechem.com/leaklock.html The HVAC and plumbing supply houses sell it. ^_^ [8~{} Uncle Leaky Monster |

A Some of the problems are caused by people putting it on backwards. Yep, I learned long ago it has to be put on so it dont unwrap when the pipe is scrrewed into the fitting. |

A Some of the problems are caused by people putting it on backwards. True - but even "properly" installed it can scred - particularly on crappy chinese black pipe with "ripped" threads. |

the yellow Teflon tape has more parts of Teflon per cm than the white tape. You should use yellow for gas and not the white. -- posted from http://www.homeownershub.com/mainten...ipe-62971-.htm |
