Hi again
Yep I made the cardboard kit from pictures. The accessory that you asked about is a vaporizer. You put the hose on the exhaust, put moth crystals in the vaporizer and blow the vapour into a closet to kill moths and protect clothing in storage.
On the plastic hose, a heat gun used carefully will loosen the solvent. You would probably have to cut the ends off the other one. The picture is a bit small but it could be a premier hose.
