Shut-Off Valve on Male Adapter won't stop dripping

Hello,

I have soldered on 4 male adapters for the hot & cold water pipes going to my bathroom & kitchen. On the male adapter threads I have wrapped around teflon tapes going around the adapter threads 3 times. I've then screwed on each of the shutoff valves to the male adapters & each one has a small, very small, leak from where the shutoff valve is screwed on to the male adapter. What am I missing? How can I put these screw on shut off valves to the male adapters without them leaking in any way?

(The soldered connections are just fine. It's leaking from the threading.)

You might want to try using a joint compound rather than the teflon tape. Sometimes the compound works better than the tape.Neither are intended "seal" a leak but designed provide lubrication to allow the threads to mesh properly. There may also be a difference in the depth of the threads between the shut-off valve and the male adapter. Good luck with your project.

Leaking valves

What I think has hppened is that you have tightened the valves too much I assume that they are brass? Take the valves off then rap 6 turns of teflon around them, add pipe dope and re install, be easy, you can always tighten more but not less. Lots of luck.
