The problem with Teflon tape is in its proper application. If it's put on a fitting leaving the first few threads bare, it will will work just fine. The problem arises when it is applied too near or on the end of the mating surfaces and small pieces tear off that tend to get caught in fuel valves, orifices, carburetor jets and and anything else that could get plugged up. It can also hold open N/C solenoid air valves in a control system. It's a simple thing to apply it right but its just as simple to screw it up if your not careful. I made a lot of money in my job removing little gobs of the stuff from many types of equipment. Also the FAA has come to the same conclusion and I know there's a FAR forbidding its use in the solid tape form although they do allow the liquid type.Geico266 said:
