Pipe joint compound or Teflon tape
Teflon tape can be used on any type of liquid joint. However, it is strictly speaking a lubricant, NOT a sealant, and is a cheap and nasty way of sealing joints. - The proper sealant for any liquid pipe joint is a pipe joint compound such as Whitlam's or Oatey's Blue Joint Compound.
Plumbers tape and Teflon tape are both used to seal pipe joints, but they have different compositions. Plumbers tape is made of a thin metal strip, while Teflon tape is made of a thin, flexible material. Teflon tape is more effective for sealing pipe joints because it is more flexible and can conform to the shape of the joint better, creating a tighter seal.
The best method for sealing pipe joints is using Teflon tape.
Welding, Brazing ,threading with Teflon tape (unless it is gas)
pipe dope and teflon tape
Using white Teflon tape on a natural gas pipe is not recommended because it is not suitable for use with gas fittings. Teflon tape is typically used for water piping applications. It may not provide the proper seal for natural gas, leading to potential leaks and safety hazards. It is best to use yellow Teflon tape or an approved pipe joint compound specifically designed for natural gas applications.
when joining to lengths of black steel it is necessary to use either Teflon tape or pipe dope, also called leak lock, this is not to seal the joint per say but the tape and doping act as a lubricant on the threads of the joint allowing for the pipe to be turned together tighter also the dope will dry and become a sealant
No, teflon tape is not sticky and that's for a good reason. -Most people think of teflon tape as a sealant. However it was originally intended for plumbing use as a sealant AND a lubricant so you can get a tighter connection on the pipe joint.
Typically, 3 to 5 wraps of Teflon tape should be used when sealing pipe fittings.
Teflon tape only, no joint compound. Two or three wraps is plenty... Yes agreed, teflon tape will make it easier for repairs in the future
If you are running natural gas or propane, gas teflon tape. Otherwise, any white teflon plumbers tape is fine.
