When installing new heater hose fittings (nipples) into an aluminum water pump housing, should anything be used on the threads like Teflon tape or pipe joint compound?

It can't hurt even though they are NPT (tapered interference) threads that should seal without using a sealer shruggy

This stuff. Just don't over-torque the fitting, it isn't necessary and it'll be a devil to get out later.

I use a brush-on pipe sealant - auto parts or hardware store stuff - because I don't want to see tape, but either is fine for pipe threads.
Don't need to glob it on, just a thin smear.
I suppose anti-sieze would also work.

i like to use Loctite #567 teflon paste. this stuff works great on every kind of fitting, every kind of fluid or gas.
i have been using it for years.

I use the Loctite too, not a huge fan of teflon tape.

For water:
Any brand of Ptfe pipe dope available in the plumbing section of any hardware store. Oatey is probably the most common brand.

For fuel:
Should use a sealant that specifies for use with gasoline such as Permatex #3. For what it's worth, I have used the plumbing stuff with gasoline lines without problems but it is not speced for that.

Avoid the Ptfe tape for anything but especially do not use for gas. Small pieces can/will tear off and wind up fouling needles and seats, jets or any fuel restrictions or passages in a carb .

In theory, there is no difference between theory and practice. In practice, there is.
