[AT] Teflon tape hydraulic system??

I recently split 2 male quick connect ends on hoses with teflon paste.

Many of the problems of tape breaking off is due to poor installation. Not sure I would leave 2 threads w/o tape, but agree that 1 thread without tape is much better than a little tape hanging over the thread.

If you have a system with fancy control valve and variable flow pumps, you should not be using pipe thread connections, with the possible exception of a pressure gauge. Other types of connections do not need tape if the fittings are good.
