Teflon

Yes

Use PASTE aka pipe dope. Any Teflon tape that is introduced into a hydraulic system can cause all kinds of problems. Tape can cause valves to not seat properly, allowing leakage, or bypass. Pumps can get damaged from tape also. Play it safe and use paste, if it does enter the hydraulic system, it will pass through the components and then get captured by the filter.

The use of PTFE tape depends on the what you'll be using it for. PVC products dont need as much as what a brass or copper fitting may require

Although Teflon has certain advantages due to its non-stick proprieties, you should keep in mind that it has consecuences on your health.

At high temperatures cookware coated with Teflon and other non-stick surfaces can break apart and emits toxic particles and gases. The fumes can sick people, but pet birds are even more sensitive. In cases of "Teflon toxicosis," as the bird poisonings are called, the lungs of exposed birds hemorrhage and fill with blood, leading to suffocation. DuPont studies show that the fumes can also sicken people, a condition called "polymer fume fever." The government has not assessed human health risks or the incidence of polymer fume fever from kitchen exposures to these particles and gases when pans are overheated.

Non-stick coatings can contain residues of PFOA (perfluorooctanoate), a chemical used to make Teflon and a breakdown product of stain- and grease-proof coatings on carpet, clothing and food packaging. PFOA is found in the bodies of nearly all Americans. It is a likely human carcinogen; it also has a variety of metabolic developmental, reproductive, endocrine, and neurobiological health effects. Many manufacturers of non-stick cookware have committed to eliminating PFOA residues from non-stick coatings. Available data suggest that non-stick pans are not a major source of PFOA in people's bodies. These exposures are more likely to come from stain- and grease-proof coatings on furniture, clothing, and food packaging.

Studies also show that most of the potential health risks from non-stick pans, such as polymer fume fever, come not from PFOA but from other particles and fumes that can come off the pan when it is overheated. While EWG continues to track the changes in manufacturing practices for non-stick cookware, we highly recommend stainless steel and cast iron as great alternatives to non-stick cooking surface.

Teflon is made up of molecules called polytetrafluoroethylene (PTFE), which is a type of synthetic fluoropolymer. It is composed of carbon and fluorine atoms arranged in a specific structure that gives it unique non-stick and heat-resistant properties.

The chemical equation for Teflon production involves the polymerization of tetrafluoroethylene (TFE) monomers. This process typically involves the reaction of TFE with a perfluorinated carbon compound in the presence of a free radical initiator to form a long chain polymer known as polytetrafluoroethylene (PTFE), which is the main component of Teflon.

Yes, but you shouldn't. Overheating teflon releases poison chemicals, and therefore if you use them at all it shouldn't be something hot like this. Try iron or steel pans for igniting a dessert and burning off rum.

yes it can yes it can

Maybe you should ask a doctor instead of an extremely uneliable website in which questions are answered by kids with nothing better to do than think up hilarious answers to things that may matter to you :).

The chemical name for the polymer is polytetrafluoroethylene (PTFE).

Polyethylene glycol does not react with Teflon (polytetrafluoroethylene) due to the non-reactive nature of Teflon. Both compounds are chemically inert and do not readily participate in chemical reactions with each other.

Yes, you can. I had this very same question myself a few days ago. In order to answer it, I put a piece of teflon tape in the flame of a propane torch. It shriveled, but did not burn or melt and when I stretched it out, it returned to its original shape. I then made a sweat joint inches from a teflon wrapped joint with no problems.

You sure want to be carfeul when doing this though. Teflon gives off extremely toxic gas if you melt it.

yes, steel will give you a better taste, allows things to brown faster,

wont Smoke at high heat,

teflon will come off after a while, and will scratch easly

First, make sure the pipe threads are clean and in good condition. Hold the end of the tape flat against the pipe threads, flush with the end of the pipe, then turn the pipe clockwise, or as though you were tightening it. Put 1-1/2 to 2 turns of tape on the pipe, keeping the tape flat and tight against the pipe as you turn, then thread the pipe immediately into the fitting. The reason for doing it this way is so the loose end gets pinned down by the action of screwing the pipe in, rather than getting flipped up.

Push on joints in piping refer to a type of mechanical joint that allows for the quick and easy connection of pipes without the need for additional fittings or adhesives. These joints typically use a rubber gasket to create a watertight seal, enabling the pipes to be pushed together and locked in place. This method is commonly used in various plumbing and drainage applications due to its simplicity and efficiency, as it reduces installation time and labor costs. Push on joints are particularly popular in PVC and other plastic piping systems.

Not a good idea to connect Copper to Steel (Hopefully Galvanized (sp)) Many products are available. Check out any hardware store or home improvement center. (New Commentator) Rarely is Teflon tape a good idea. A fragment can and will break off, affecting something down the line.(valves,gauges,etc.) "Dope" is usually a better solution.(we are speaking of pipe dope here) What the earlier commentator what trying to get you to understand, is that when two metals meet, a battery is created. Steel and copper will interact with each other even on a low temperature(lower energy)line. Both materials will be affected,corroded, and your line will eventually clog,as it rots. Uniform materials might seem less expensive in the short term, but, in the long term, which depending on a number of variables, may only a few years, can cause a complete do over. (Very expensive) Prior commentator was hoping at least, you meant galvanized steel, because, the death of your pipes will be delayed a bit. If you can,change the female to copper. Just make sure the wall is thick enough. Try to use 'western' plumbing materials. There is a reason they cost more, and most of that reason is more uniform standards, better casts, threads that actually make a secure join, and try to stay away from the plastics. If you do the job right, you shouldn't have to do it again.

I'm assuming you mean house pipe joints. Start at the pipe union, using a bigger pipe wrench if necessary. If the joint breaks you will have to replace the pipe. Unfortunately there aren't any real good tricks, it just takes a lot of force. you can try draining the pipe and adding heat, but don't get it hot enough to melt the galvanized coating otherwise you'll NEVER get the pipe off. If it's a gas pipe don't try putting heat on the line. That wouldn't be good.

No sane person on earth is going to believe that the government is going to "mandate the use of Teflon in every cooking item." That's what the most recent answer to this said, and that's the most ridiculous thing I have heard in a long time. I thought it was a joke until I read every word of that answer: the person who wrote it seems to think that the government will force companies to put Teflon on cooking items in order to reduce the world's population. That's right. How, you might wonder, could that be? Well, Teflon's chemical breakdown products may be carcinogenic, and there are genuine concerns about Teflon for several reasons. People coming to this page here are probably already convinced of that. But apparently there do exist people who are a little more extreme, who imagine that this danger is so great that the government will take advantage of that menace by requiring Teflon on everything in the kitchen in order to sicken enough people that we'll all start dropping dead from Teflon related illnesses, and there will be fewer people in the world. You may not have heard of them, but there really do exist people who, similarly, believe that vaccines are a plot, not to prevent disease, but to kill as many people as possible. There really are people who believe that.

I'm praying that the answer that was put here at first was satire, not literal belief....I love satire also, but I don't think that it belongs here on Wiki.

Well, Teflon is an item of concern: I don't allow it in my house because of PTFE toxicosis--sensitivity of birds to Teflon fumes. The Environmental Working Group is concerned about it, as are lots of other consumer groups.

That the government would "mandate" all cooking utensils be Teflon coated is obviously absurd, if for no reason other than the fact that not every cooking utensil in the kitchen can be coated with teflon: according to the manufacturer, "DuPont™ Teflon® industrial coatings can be used on carbon steel, aluminum, stainless steel, steel alloys, brass, and magnesium, as well as non-metallics such as glass, fiberglass, some rubber, and plastics." So you're going to find it difficult to imagine that the government could mandate something such as coating cast iron skillets with Teflon®.

Here's the original answer; I'm leaving it up because this answer is linked to at other sites, and people coming to this page deserve an explanation: "Nope, the government is mandating the use of teflon in every cooking item. It is now up for review and could become law. If a company makes an item without teflon or you cook without teflon you could face criminal charges. I guess that's why there aren't any companies making bread machines without it. Since there are countless people including myself that want to buy a bread machine without the toxic teflon crap, this is the only reason I can come up with. I think it's part of the strategy to help keep the world's population lower. Teflon will cause cancer and a host of other dangerous health problems..... why not incorporate it into everything?"

The Bready Bread Machine mentioned in the 7/18/11 addendum to this answer DOES have a non-stick coating of some sort: "A non-stick bake pan allows your bread to roll out effortlessly onto a cooling rack." Their website doesn't say whether it is Teflon or one of the other coatings. Someone apparently thought that the laws of chemistry are somehow different in Sweden than they are elsewhere. The previous answer stated, "it looks to get around the teflon issue because it was engineered in Sweden."
