Replacing the PRV on my 10 gal Atwood. Would it be wise or not to use some plumber putty on the new one?

It's not supposed to be needed when using soft brass threads in soft aluminum sidewalls, but I always apply either teflon tape or plumbers putty. Can't hurt as long as it is rated for hot water use.

I also use a teflon tape on all of those kinds of connections. Not only does it add a bit of mental security to having made a good seal, I think the threads mesh a bit smoother and makes the connection a smoother operation.

Pipe threads are tapered and intended to be metal/metal. Teflon tape adds little to a seal, but acts as a lubricant to allow the male to enter further. However, a seal will only occur if the tape is cut by the threaded parts, allowing metal/metal contact.
