[AT] Hydraulic fittings

[charliehill]

I almost never use teflon tape except on simple water fittings.  I like the 
paste better. Dennis I agree that you are technically correct but I 
sometimes put the Teflon paste somewhere where it doesn't belong or is not 
required as a "backstop", if you will, for a messed up thread or whatever. 
It might not help but it won't hurt either.  I've even put paste on ferrule 
fittings on oil lines, on the thread and on the back side of the ferrule.  I 
know that doesn't make sense but when it's below freezing outside and you've 
got a problem with your fuel oil supply line and don't want it sucking air 
that little bit of paste MAY make the difference.

If you are working with all new parts,  have the proper parts for the job, 
and have time to test your  fittings it's not necessary but when you're 
working with what you have on hand in less than desireable conditions and 
need to get up and running it's worth trying the Teflon.
