Default Anything on the threads?

Putting a brass threaded fitting into aluminum intake manifold? Should I use Teflon tape or anything else?

I use anti-seize compound for brass fittings into aluminum. Been doing that for 60 years without issues. If the fitting is a gauge sender, the Teflon tape might insulate it and it may not function. Others may have different experiences......

Best thing I've found is a teflon based pipe dope... Teflon tape can cause problems is used incorrectly. And you won't need much of whatever you choose to use.

tape is acceptable but the paste is the preferred sealant lubes the thread stops galling and thread binding [protects the thread] and allows the threads to seal at a much lower torque [win win win ]
