|In response to Re: teflon tape on black iron gas pipe|
Teflon tape is made from pure teflon, it is impervious to all components of natural gas and almost everything else. I have seen tape that was colored Pink, and green. Ihave never seen yellow.
Teflon tape on steel tapered pipe threads is an excellent sealant IF......... you tighten the joint sufficiently and slowly enough to allow the teflon to flow. We use steel tapered pipe threads routinely to 15000 psi with no leak problems.
: : : I had a gas line and meter installed and put together a gas distribution system. Unfortunately, I cannot get it to pressurize. It slowly leaks down in spite of all the soapy water on all the joints that show no discernible leaks. I have been told that it is because I used the wrong type of teflon tape - the white stuff which is gas permeable rather than the yellow "gas" stuff. I was also told that my installation would be rejected by the inspector anyway because of the use of the "wrong type of tape" and that I should tear the whole system apart and either use the yellow gas tape or, use a gas approved dope. Is this correct or is this Eagle Hardware fantasy?
