P138 Serrated Separating Roller Ring - Silicone Rubber - Bag of 20
This is a bag of 20 silicone disks that affix to the separating roller. One roller holds 10 pieces, so one bag can do two change-outs. See part P136 for a full separating roller with roller rings.
The serrated rollers allow for the separating roller to make less contact with the tape. The tape rides on the points of the ring instead of the full surface of the standard ring. It can help with dispensing tackier tapes.
