Gobs of Teflon tape aren't likely to stop the leakage. Since brass is
so easily deformed, it makes more sense to simply buy another fitting.
Another sneaky trick is to use automtive sealants instead of pipe dope.
Permatex #3, Hylomar, and others are especially well suited to handling
hot water. You'll need to thoroughly clean off the pipe dope for the
sealants to work well. HTH
