TT Weights Moments Turntable "O" Ring

My understanding is that TT WEIGHTS is no longer in business. Can anyone advise me on how to get a silicone "O" ring for the table. I sent an inquiry  to Larry but I have not heard anything as yet.
My ring is good for  now.  Eventually, I would expect that it would dry out(dry rot).
Thanks in advance for any help you can give.

Pardon the misspell !
I made my own buying O-ring material and special silicone glue from McMaster- Carr.  I don't know how it would compare to the TT-Weights product, but it didn't cost much to try.  I have a heavy platter Lenco and didn't hear a difference using multiple rings.  I do always use the TT-Weights clamping ring to flatten records and sometimes improve tone stability though.

I also have a TT Weights turntable.  I just some belts from this company:

Just go down the list and you should find a size similar to yours.
