Our O-Rings are specially designed for ONSRA electric skateboards. They are a mechanical gasket, in the shape of a torus (a loop of elastomer with a circular cross-section) that is placed in between the deck and the enclosure of the skateboard.

This helps to provide a secure seal and prevent any unwanted movement or vibration that could affect the performance of your skateboard. The O-Rings are made of high-quality elastomer, which is known for its excellent resistance to wear and tear, and its ability to maintain its shape and flexibility over time, ensuring that the O-Rings will remain in place and continue to provide a secure seal, even after prolonged use. They are easy to install and replace, making it convenient for regular maintenance and upkeep of your ONSRA electric skateboard.
