O-rings are color coded by size, eliminating the headache of matching up sizes.
Included color/size chart helps with your first time rebuilding your marker. After that, just replace orings by color when it comes time to rebuild again.
All of the o-rings you need to perform a standard rebuild of your marker three times (other quantities available).
Note: The product image associated with this item is a sample only. You will receive the kit for your specific marker that you order which will contain the o-rings needed for that marker.
