Replace kitchen faucet, use teflon tape or not..or plumbers putty?

Question

I'm trying to replace a kitchen faucet, and am replacing the hot and cold supply lines also. I've got the stainless steel supply lines to replace the old ones. Should I use teflon tape when connecting the new ones? Or plumbers putty? What is the difference? What happens if I don't use anything?

Answer 1

Plumber's putty is a putty or clay like substance. Teflon tape is usually a thin white flimsy tape. Both are used to seal things to keep them from leaking, but in different ways.



Use teflon tape on the threaded connections. Wrap it so that when you're tightening the nut, it pulls the tape tighter, not looser. When you tighten the connection, it fills the voids between the threads to keep water from seeping through there.



Use plumber's putty underneath the faucet body when you put it onto the sink. It helps seal under the faucet to keep water from running under it and dripping into the cabinet inside. Usually you roll it between your hands and make a rope or snake of it, and position it at the edge of the faucet body. Then when you tighten the nuts, some squeezes out. Scrape away this part and toss it in the trash. What remains will seal the faucet.

Answer 3

The stainless steel supply lines have a rubber cone washer built in to each end. You do not need any teflon tape or pipe dope on any of the connections. Plumbers putty is used when you are installing the basket strainers to make a seal between the sink and the strainer. You also use the putty if the faucet does not have a gasket and also under the spray holder or soap dispenser.

Answer 5

Plumbers Tape

Answer 6

Plumbers putty is for another application usually to rim a sink. Threads are another situation and require teflon tape or pipe dope. If your using stainless flex lines just a little pipe dope is required on the threads for lubrication. If its actual pipe threads use teflon tape wind the tape about three turns the same direction your tightening the other way will strip it off. If you dont use any there is a chance for leaks

Answer 7

If it is a threaded connection use teflon tape. You could also use pipe joint compound (which is not plumbers putty) which seems to me to be a mix of some sort of clay compound and linseed oil. Teflon tape is neater.



Plumbers putty is something else altogether.

Answer 8

Use the tape,wrap it three times. I have replaced mine ,and never used anything. Plumbers putty is used for things like setting a sink into place, putting a flange into a sink,that kind of stuff. It doesn't work well on things you need to screw on.

Answer 9

The connections at the sink are brass. You do not need tape or pipe joint compound. Pipe joint compound or tape is used on black, galvanized, and threaded copper pipe to keep the joints from corroding together so if needed you may unscrew them at a later time, the also help seal the joint.

Answer 10

Just put teflon tape on the threads and you'll be fine.

You can try teflon pipe dope. Don't use the "brown" stuff for gas lines, as it gets rather hard over time and is a hard to get off.
