Cannot find an ABS internal coupling for repair or extension of 2-inch ABS DWV pipe, which would typically require reducing internal diameter or lacking depth stop, making it unavailable and possibly against code.

Existing solutions involve drilling out old pipe or using reducers, which are workarounds rather than a dedicated internal coupling, and may not provide a secure, code-compliant connection.
