These custom o-rings were designed specifically for fingerboarding! Each o-ring is made from silicone, the same material used in most professional shaped tuning. Our silicone o-rings are high quality o-rings that last a long time, have a soft yet strong durometer, and come in our own custom colors (some of which you can’t find anywhere else!).
Each pack includes 20 o-rings. Colors are mixed and random.
Each o-ring has an outer diameter of 4mm, an inner diameter of 1.5mm, and a thickness of 1.5mm. The perfect size for your fingerboard trucks.
Washers are not included but are recommended.
These o-ring packs can be used for personal use or resold under your own brand. If you would like a 20-pack of one single color, check out our other o-ring product listing for a discounted price.
