Hi Gina,
I'm not so sure this is the case. Fred gave a class some time back
wherein he espoused the value of teflon centers. He dropped a hammer and
flange into a glass of water at the beginning of the class. At the end
of the class, he pulled it out of the water and showed that it had the
same tightness as before it got doused.

I know that there are problems with teflon and I'm not an advocate of
teflon but I do wonder what was proven by that test.

Regards,
Tom
