Rubber O Rings are key sealing components widely used in the automotive industry to provide waterproof, dustproof, and sealing functions between connecting components. These O-rings are typically made of soft and elastic rubber materials, such as nitrile rubber, fluororubber, or silicone rubber, to ensure their ability to withstand high temperatures and pressures in automotive engines, transmissions, braking systems, and other critical components. The design and manufacturing of custom rubber O rings usually follow strict standards to ensure their reliable sealing performance and durability. These sealing rings can fill the gaps between connecting components, prevent liquid or gas leakage, and reduce wear caused by vibration and mechanical movement.
