Pneumatic Vacuum Cups BH-50 Qty 10 New

This item was purchased from a large business inventory reduction sale. They are also labeled, "Y7931-91013B4-50". It does not show the brand name. I do not know the history or age of them, but they were most likely spares. They look fresh and new and they are not dried out. I am not able to test them. It only comes with what is shown in the pictures.
