tuba mouthpieces with threaded rims

In any event...a thin, inexpensive strip of teflon tape applied in the way Bloke described may be of some benefit and CERTAINLY wouldn't hurt anything.

Todd, conceding the point.

Would heavier lead tape be useful to improve the tone?

Yes, if you swallow it.

That may be true for the stainless steel pieces you use, but...

I have been making (brass) screw rims for trombone and tuba mouthpieces for 27 years (and a few for trumpet many years ago, but no more). I have always used the same pitch thread for all of them. There is no reason to use different tolerances or fit for different diameters. The same clearance will work equally well at any diameter. And the sealing surfaces are not the threads, so there's no reason to use teflon tape either, unless it's for ease of disassembly. And my threads are a tight enough fit that I don't think there would be room for teflon tape, although I've never tried it.

Teflon tape or thread sealing compound is necessary on tapered threads like pipe threads, under pressure, because the seal is the threads themselves.

I currently use three makes of screw-rim mouthpieces: Doug Elliott, Loud, and Warburton. I have never had any problem with blow-by or seepage in any of them.

Tuba players have swallowed a lot when it comes to new, improved methods of producing a good tone.

After all you are preferable with rather than without. At least in a tuba, and in a seeping, context.
