Can you use pipe dope for water lines?
1 Answer. no – pipe dope can pretty much be used everywhere. its not necessary though on anything but a thread to thread seal. most vanities nowadays use flexible supply lines that have compression type fittings at either end with a rubber seal in them.

Can I use both Teflon tape and pipe dope together?
Teflon tape should never be used for gas piping unless it is yellow rated. Using Dope and tape together is how it should be done. Dope has Teflon embedded in it and acts as lubricant and Bonds with the Teflon tape making a great seal.
Do you use Teflon tape on water supply lines?
Most faucets will have hot and cold water supply lines attached, so you just need to connect them to the appropriate water supply line. You may need to use Teflon tape (aka plumber’s tape) for this part, which is used to seal and lubricate threaded pipe joints.
Is it better to use Teflon tape or pipe dope?
Pipe joint compound is easy to find, fairly simple to use, and inexpensive. It works with all types of pipe and fitting materials, and it produces a strong seal. Pipe dope is generally stronger seal than Teflon tape, which is why plumbers and other professionals use it rather than tape for seals that are permanent.
Should I use Teflon tape and pipe dope?
Don’t use Teflon tape, Teflon paste or pipe dope. Do use a sealant. Teflon tape, Teflon paste and pipe dope is intended for metal pipe and fittings. Metal to metal fitting joints are more difficult to tighten than plastic; the surfaces tend to gall without the aid of such lubricants as Teflon or pipe dope.
Does pipe dope go bad?
Re: Does Pipe Joint Compound expire or go bad? pipe dope, over time, separates. so I suppose if the tube is still plenty pliable and you can squish it back and forth to get it into its intended form, it is still good.
Is pipe dope a sealant or lubricant?
Pipe dope is any thread lubricant, thread sealing compound, or anaerobic chemical sealant that is used to make a pipe thread joint leak proof and pressure tight. The application of pipe dope prior to assembly will fill the minute voids between the threads, thus making the joint pressure tight.
Is pipe dope the same as thread sealant?
Pipe dope, pipe joint compound, pipe thread seal—these are all different names for products used to create fluid-tight seals in threaded pipe joints.
Do you use pipe dope on flexible gas line?
It states that it is ok to use pipe dope on the fittings of a gas line, but not on the first two threads.
How many times do you wrap Teflon tape?
How many times should I wrap the tape around? When using 3.5 mil tape on pipe sizes up to 1¼”, three revolutions should do it. Beyond that, you’re just wasting your customer’s time — and your own. A 3.0 mil tape needs four to five full wraps around the pipe end.
When should you not use Teflon tape?
An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly.
How tight should water supply lines be?
Hand Tight is Right. In fact, pipes should only be hand tight to help aid the flow of water throughout your home. The unique construction and configuration of pipes means they are made to be tightened just enough; making them super tight can actually prevent water from flowing properly.
Do braided lines need Teflon tape?
Braided supply lines do not need either. They have a built in gasket to do the sealing. Wrench a quarter or half turn beyond finger tight and you should be good. No sealant is required on the tailpiece joint, but it won’t hurt.
Can you connect two water supply lines?
The easiest way to connect faucet water supply lines together is by using a compression fitting. Measure your line diameters carefully and purchase the same size compression fitting to join them. Push-in fittings, though, may also be used, although they are not necessary with copper tubes.
