Ryobi Stick vac attachment coupler inner and outer available

Vacuum shown is the ryobi dual roller pet vacuum PBLSV717B

For whatever reason, ryobi made the diameter of the vacuum end the same as common attachments, so you can't use them together.

This is a tapered coupler, both inner and outer options available, for desired airflow.

inner coupler transitions from 31 to 32 mm over 42mm and 32mm along the adapter.
outer coupler transitions from 35 to 37 mm over 30mm, this one is symmetrical.
