The Tusa Ortho Mouth Piece is identified by Tusa manufacturer part number TC-606 and UPC barcode 685193450117. Use this part number when ordering or confirming you are getting the genuine Tusa replacement mouthpiece rather than a generic aftermarket substitute.
Will this mouthpiece fit my Tusa regulator?

Why would I need to replace my regulator mouthpiece?
