anti-sieze too many choices

[robert mueller]

Scott,

Those parts are National Pipe Thread and I always use Teflon tape on NPT threads.

Would the nickel silver anti seize be good for the oil sending unit and the water temp probe?

On sending units I use the silver stuff Advanced gives you with new sparking plugs. Not a Teflon fan where conductivity is needed.

I've never had a problem with the teflon paste on senders. When you thread it in, enough of it gets squeezed out from where it is metal on metal that
there is good contact. The paste only fills the gaps. No metal to metal contact at the gaps anyway. And if your threads are so shot that there is
no metal on metal, you have other problems...

Same with me--I use teflon tape, being very careful not to let it overlap
the tip where it can come off in the system. I've never had a problem with
electrical connections.

Rich,

Teflon tape on fitting should start 1 to 1 1/2 threads from the end of the fittings and there should be no more than two wraps.

In case ya'll were wondering that career field included the following aircraft systems: air conditioning, pressurization, engine
bleed air, flight surface anti-icing, oxygen (liquid & gaseous), pneumatic powered constant speed generator drives, engine starters.

Anything else (non Avionic) that the electrical or hydraulic shops didn't repair.

Rich,

Rob’s explanation on how to use teflon tape be it the thin, or heavier or the yellow tape is an excellent method to follow. The company that I worked for 34 years (Retired 2006), DOW about 25 years ago banned the use of teflon tape in air and instrument process control equipment as we were finding it downstream of the point of installation and into the process control systems and measurement instruments. I still only use the paste on most applications and do use the tape on some applications. If you take a fitting apart be sure to clean the threads of a shreds of teflon tape.

Rob, you actually have your MI and TI books is great, I want to keep mine but some of the AFSC 40270 Photographic Systems Technician book sections were classified Secret, but today all of the stuff has been declassified and some has appeared in Popular Science.
