This is a Custom Automotive Lens Sealing Ring. It’s a pure black regular circular rubber component. It’s manufactured via peroxide vulcanization. Its hardness is 70±5°A.It has a uniformly neat annular contour. Its cross-sectional thickness is consistent. It has a rigid shape (high hardness and peroxide vulcanization bring excellent structural stability). Its surface presents a delicate semi-matte texture. It has a uniformly dense luster unique to peroxide vulcanization. The edges undergo precision polishing. They are smooth and clean. There are no burrs or micro-defects. A single piece maintains a regular annular form. Multiple pieces stacked won’t collapse or deform. It serves as a customized precision sealing accessory specifically tailored for automotive lenses.As a core customized protection component for automotive optical systems, it is an integral part of
Automotive Sealing Assemblie and
Automotive Sealing Solution. It meets the precision standards of
Precision automotive seal and
Car Camera Silicone Seals.
Product Features
1. Function:As the "customized core protection component" for on-board lenses, its primary role is to match the interface dimensions and mounting grooves of exclusive automotive lenses precisely. It constructs an integrated protection system of high-density sealing + stable positioning.Through the high-hardness annular structure reinforced by peroxide vulcanization, it fits the customized gaps between the lens and the mounting base tightly. It completely blocks the intrusion of rainwater, high-pressure car wash water, road dust, and moisture. This avoids fogging of optical components and dampness-induced short circuits of circuits. It relies on customized dimensional precision and high-hardness shape stability. It provides accurate installation and positioning support for the lens. It buffers vibration impacts during vehicle operation. It reduces interface wear.This ensures the imaging accuracy and long-term operational reliability of exclusive on-board lenses under complex road conditions and extreme climates. Its customized protective function matches the requirements of
Precision Seals for Car Lenses and
Automotive Camera Module Sealing Ring in high-end automotive optical systems.

2. Performance Characteristics
1)Precision Customized Adaptation with Zero DeviationIt is developed based on the exclusive interface parameters of on-board lenses. Its dimensions and annular contour match the mounting grooves perfectly. It solves the adaptation deviation problem of universal seals. The 70±5°A hardness combined with the structural stability of peroxide vulcanization ensures no displacement or loosening after installation. It meets the assembly needs of customized lenses perfectly. This precision is like the manufacturing standards of Precision
Automotive Seal and high-precision customized automotive components.
2)Dual Empowerment of Peroxide Vulcanization + High HardnessPeroxide vulcanization achieves more uniform crosslinking of rubber molecules. It also upgrades structural density. Combined with 70±5°A high hardness, it achieves IP67-level waterproof sealing. It resists high-pressure water impact, long-term splashing, and dust intrusion. It also maintains a rigid and non-collapsible annular structure. This enhances the positioning accuracy of the lens interface. It avoids seal failure caused by vibration. This performance meets the strict standards of Automotive Seal and
Lens Barrel Rubber Seals.
3)Upgraded Vibration Damping ToughnessPeroxide vulcanization optimizes the balance between material elasticity and rigidity. High hardness does not sacrifice buffering capacity. Instead, it forms a combination of "rigid support + elastic buffering". It can absorb high-frequency vibrations and strong impacts during high-speed driving, off-road jolts, and other scenarios. It reduces hard friction between the lens and the mounting base. It prevents displacement of optical components or loosening of interfaces. This damping performance meets the dynamic requirements of Automotive Camera Module Sealing Ring and high-performance automotive optical components.
4)Outstanding Weather Resistance and Anti-aging PerformancePeroxide vulcanization improves the anti-aging stability of the material. Combined with 70±5°A hardness and rubber substrate adapted for automotive scenarios, it withstands an extreme temperature range of -45℃~135℃. It does not harden, become brittle, or collapse and deform under high temperatures from summer exposure. It also maintains stability in low-temperature freezing in winter. It exhibits excellent UV and ozone resistance. During long-term outdoor use, there’s no cracking or embrittlement. Its service life is synchronously improved with lens adaptability. This environmental adaptability meets the durability requirements of Car Camera Silicone Seals and automotive outdoor sealing components.
5)Wear-Resistant, Easy-to-Install, and Component-ProtectiveThe high-hardness material combined with the dense structure from peroxide vulcanization significantly enhances surface wear resistance. It can withstand slight friction during installation and use. It tolerates common automotive media such as oil stains and car wash cleaners. There’s no swelling or performance degradation after contact. The edges undergo precision polishing. They are smooth and have no burrs. During assembly, it can be embedded into customized grooves easily. It won’t scratch the lens or mounting base surface. This user-friendly design meets the installation and protection requirements of Automotive Sealing Solution and integrated automotive sealing systems.
