teflon tape vs pipe tape ???
what is the difference between teflon tape and pipe tape?
I was at the hardware store and they had teflon (in a blue spool) and pipe tape in a red spool. Also yellow for gas but i know what that is for my question is if im joining pipes what do i want to use? Copper and brass fittings i have been using teflon WHat is pipe tape for? Is that better for galvanized or whats the deal? IM getting read to get the sawsall out and rip out all my galvanzied but there will be a few spots were i go from ABS to galvanized and need to know what type of pipe tape to use to make these connections. I will also be putting in water shutoffs and water supply lines (for water in door fridge). I just want to know what everyone uses or recommends. Thanks! |

You can use whichever you happen to like. I use yellow; it handles much better than white and means I only have to have one kind. |

strange but the yellow was labeled for gas at my home depot.
im sure they make all different colors for different applications. Toller wrote: "scale" wrote in message oups.com... what is the difference between teflon tape and pipe tape?

The colors just distinguish the thickness...the only reason yellow is "for gas" is because of the extra thickness and that's the color they chose. Same stuff, different thickness as Toller says...

Teflon is a trademark of DuPont, the generic term is PTFE, shorthand
for polytetrafluoroethylene. The only thing against it is that aluminum will react with it and it will decay, so use pipe dope for aluminum.-Jitney |

If you use any kind of Teflon tape on a gas line and there is a warranty
claim on anything downstream of that taped fitting, there may be a problem. Manufacturers will occasionally inspect gas valves, etc to see what caused the failure. If any bits of Teflon tape is found in the valve, that warranty will be voided. Teflon tape does break up fairly easily and gets into the inner workings of the valves. That tiny piece of tape can cause a problem. "scale" wrote in message oups.com... what is the difference between teflon tape and pipe tape?

teflon tape vs pipe tape ???
I picked it up off the sci.chem group about a year or two ago. He said
that the aluminum metal had a high affinity for the flourine atoms on the PTFE polymer chain and that there was a transfer of some sort (I am paraphrasing). That is not my specialty but it makes sense with what I know, aluminum is a chemically active metal with some alkalinity, the only thing that makes it stable is the formation of a thin oxide surface. Flourine is active at the extreme other end of the spectrum and I think would form these compounds, its bond with the polymer chain PTFE is normally strong and stable but aluminum would be a strong attractant. I don't know if this is good enough evidence for you, a good search through the usenet archive would turn up the original post. The teflon coating on aluminum pans is admittedly a strong counterindicator, though. I could research it further, but it is easier for me to just use pipe dope on aluminum.-Jitney |

I see it some on car and motorcycle engines, and some heat exchangers.
Not much else, but Gore-Tex offers its PTFE product for wire insulation, and there is some aluminum wire here and there. I hope some electrical engineers are reading this...-Jitney |

There is no such thing as teflon tape: from DuPont: "€˘ 1938 €” Dr. Roy Plunkett, a DuPont scientist, discovered polytetrafluoroethylene (PTFE). €˘ 1946 €” DuPont registers the trademark, Teflon® for PTFE.Dr. Roy Plunkett | DuPont„˘ Teflon® PTFE €˘ Late 1940s €” DuPont began marketing PTFE on a small scale for certain industrial applications, including valves, o-rings, and pipe linings. €˘ 1969 €” DuPont PTFE fine powder is used for plumber tape for sealing joints in piping and central heating systems. However, DuPont never manufactured the tape. The manufacturers purchased and used DuPont PTFE fine powder as consumers started favouring easy to apply PTFE tape over existing solutions. Plumber tape using DuPont„˘ Teflon® PTFE fine powder was the first such product to reach consumers. €˘ Times changed, other companies started making PTFE fine powder that was of a lower quality and at a lower cost. The companies that made the plumber tape switched to the lower quality powder. They didnt have permission from DuPont to use the Teflon® brand because they no longer were using DuPont product. €˘ Separately, in the 1990s, DuPont stopped selling its PTFE product lines labeled as Teflon®, including fine powder. The reason for the change was to ensure products bearing the Teflon® brand met the highest quality standards expected by consumers. Any use of the Teflon® brand now needs written authorization from DuPont. Teflon® is a registered trademark of DuPont." -- posted from http://www.homeownershub.com/mainten...ape-47304-.htm using HomeOwnersHub's Web, RSS and Social Media Interface to home and garden related groups |
