I know there's a thread on this subject but can't seem to find it...... whats the recommended thread sealant for water & oil sender units? The gauges are electrical.I used the shellac stuff in the past but I think there is something better that is used.
Teflon tape would work but not sure it's the best sealer to chose when using with electrical senders, the copper anti-seize would have greater conductivity but does it seal out water / oil ok?
I'll check out the Permatex products too.........thanks guy's for your input.
There is absolutely no way that you can add a tape or sealant to a sender and electrically isolate it. The threads WILL make contact, metal to metal, no matter how you seal them. Don't believe it...try isolating a connection and then put a meter on the two sides, continuity will be read in every case.

Technically, pipe threads should not need any sealant at all, it's inherent to the design, but due to manufacturing intolerances sometimes it's necessary. It's been proven over and over many times that Teflon tape makes a great insulator if overly applied, as with any dielectric compound. I've been using copper anti-seize specifically for that purpose in many applications on many different engines and equipment for I don't know how long, and never had a leaking issue.
Picked up the senders I had ordered from Ford, oil has Teflon & coolant has some red sealant, guess it doesn't matter what ya use.... long as there's no leaks & the gauge works!
Thanks for posting your feedback guy's.
