The Teflon tape I bought comes with a 10,000 PSI rating. Sounds like it was designed for hydraulics. I will use care though as two of my spool vavles use Pipe threads Plus the tank.

Right you are.
I just picked this quote out of the bunch because the type of stuff I work on daily has all of those listed components, and.....the manufacturers have also used teflon tape on some of the connections.
Since I sometimes get calls on the weekends, I have 100+ of our equipment service manuals on an external hard drive to refer to if a customer has a question. I just got done choosing 5 different boom lift service manuals to scan using the "find" box to scan the .pdf manuals. I entered "teflon tape" into the search box, which then scans the entire manual for those words.
The ONLY mention in any of them cautioning against the use of teflon tape, has to do with fuel systems. Since the manufacturer is aware that teflon tape exists, (because it's used from the factory at some of the hydraulic connections), yet only cautions against its use in fuel systems.....leads me to believe that if done properly on a hydraulic connection it's a non-issue. Once again, these are boom lift service manuals....a machine that has an operator on the end of a stick 60/80/100 feet up in the air.
That power point slide show was interesting, but the "smoking gun" they uncovered could have just as easily been a piece of dirt or a sliver of an o-ring clogging up the orifice or hanging up the valve. The presentation said that the last tech to work on the system didn't use teflon tape.....but the tech before him had. Same situation could have occurred if the tech hadn't cleaned out any other debris from prior disassembly and assembly. Maybe teflon tape is prohibited in aircraft applications....I don't know. But it isn't prohibited elsewhere or the manufacturers wouldn't use it in the first place. And since the horrors that can result from its use are so "well known", they'd specifically warn against its use in the service manuals. But they don't, except for the little blurb it gets in relation to fuel systems.....an area where a failure occurring is only a minor inconvenience in comparison to what could happen with a couple of workers in the platform 100 feet up in the air and a hydraulic mishap took place.
These manuals aren't a "general" guide or anything either, they're typically 300-500 pages, with anywhere from 50-100 of those pages devoted to hydraulics specifically. Plenty of opportunity to warn against its use there, but they don't.
This is another one of those "personal" preference" things, I guess. I'm neither *for* or *against* using teflon tape on the connections in a hydraulic system. I just don't think it's an issue if it's done properly.
And the same thing can be said for a host of other products and procedures.
