How much teflon tape to use?
Posted by Andy on January 26, 19100 at 13:22:20:

For a typical 1/2" international pipe standard coarse thread, how many wraps
of teflon tape are necessary to get a good seal? Does it matter if I'm dealing with
old rusty galvanized steel threads or crisp clean brass threads? Also, does it make a
difference which kind of tape I use? I just have the regular white stuff, but I have seen
other colors like blue and pink, are they of a different thickness or designed for different
types of joints?

Thanks in advance for any advice.
