In case you lose the O-rings included with your original purchase, purchase a replacement set. Includes six O-rings (one pair each of small, medium, and large). This allows you to choose the correct O-ring size for your rod. Approximate size guide: small O-rings fit a ¼” rod, medium O-rings fit a ½” rod, and large O-rings fit up to a ¾” rod.
