Through all of this, you still expect your marker to perform week in and week out. A small bit of maintenance is key to ensuring that your marker functions and performs at its best. One major aspect of marker maintenance is replacing your o-rings. The o-rings in your marker wear down over time by withstanding thousands of cycles along with coming in contact with dirt/debris. Our kits provide an easy and inexpensive way to keep your marker in top shape by swapping out your o-rings. 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).
