Default Novarossi HS needle housing washers/seals

Hey guys,
Just noticed some leaking from my HS needle housing (the brass housing part that screws into the carb body). It is sealed via two aluminium washers from what I can see.

I had to remove it because the needle had clogged up from years without use, and now she is running beautifully, however a little bit of fuel seems to be leaking from where the aluminium washers seal.

Can I replace these (are they available readily?), or should I just hit the threads with some teflon tape to help seal it up?

The engine is a .21 JP Mod, slide carb if it matters, seems like the standard NR carby though.

It is recommended to replace the aluminum rings (shims) whenever the brass high speed housing is removed/repositioned because the rings will conform to the housing once tightened down.

Here is the part no.:
