Hi Dave,

Although it is officially a No-No, I have always used Teflon tape on my 
large pipe thread ends.  I am carefully to not wrap it so that tape is not 
near the pointed end and is wrapped tight.  I also found the fitting 
"bottoming" out in the redrive casting as if made for a straight rather than 
a tapered NPT.  This not a recommendation to use Teflon tape - just my 
experience has been OK.
