i’ve got an OR-12 in my cart, is that the same thing as the ALLIANCE PLASTICS -12 ORS cap?
Answer by: Customer Support on Apr 14, 2025, 6:43 AM
For matching and replacement, the key identifier here is the supplier part number. OR-12 is the supplier part number for the ALLIANCE PLASTICS -12 ORS CAP, so OR-12 corresponds to that cap.
