It is derived from tetrafluoroethylene (TFE) and has some unique properties that make it a useful material in a wide range of applications. For example: Very high melting point: With a melting point of around 327°C, there are very few situations where PTFE would be damaged by heat.Jul 3, 2018
Is Teflon tape flammable?
Totally maintenance free, PTFE thread sealant tape is virtually chemically inert, non-toxic, non-absorbent and non-flammable. All Tapes are rated for use in temperatures from -450 to 550 F.
Can you use Teflon tape on hot water pipes?
For threaded pipe, you should have a union on both the hot and cold water lines. ... Use Teflon tape (but not pipe dope) on the male threads entering the flex-connectors. If your water heater has female-threaded tappings, you'll need a pair of 3/4" nipples to accept the flex-connectors at the bottom.
Does Teflon tape conduct heat?
Heat Resistant PTFE has an extraordinarily high melting point for a plastic, 327 degrees Celsius or 621 degrees F. It is rated for use at temperatures up to 260 degrees Celsius, 500 degrees F. For most applications, PTFE will not degrade from exposure to heat.
What do the different colors of Teflon tape mean?
Thread tape comes in different colors for different uses. White tape is single density and intended for water pipes of 3/8 of an inch or less. ... Yellow tape is double density, and designed for gas and fuel lines. Green tape is grease and oil free, and designed for pipes carrying oxygen.
