This automotive lens O-ring is made of EPDM. Its hardness is 70A. It has a pure black annular structure.Its surface is delicate and matte. Its cross-sectional thickness is uniform. Its edges are finely processed. The edges are regular, with no burrs. Its overall dimensional precision is extremely strict. This lets it be clamped accurately into the sealing groove of automotive lenses. It serves as a core precision accessory. It ensures the waterproof and dustproof performance of on-board lenses.As a key sealing 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:The EPDM automotive lens O-ring is mainly used to fill gaps in the sealing grooves of on-board lenses.It achieves high-airtightness protection through tight fitting. It blocks rainwater, dust, sand, and road moisture from entering the lens interior. This prevents electronic components from being dampened, contaminated, or short-circuited. It ensures the stable operation of on-board cameras under complex road conditions such as rainy days, sandstorms, and high-temperature exposure. It also maintains imaging accuracy and equipment service life.Its sealing function matches the protective requirements of
Precision Seals for Car Lenses and
Automotive Camera Module Sealing Ring in automotive optical systems.
2. Performance Characteristics
1)Strong Sealing ReliabilityThe 70A hardness EPDM material has excellent elasticity. This lets it fit tightly into the sealing groove. It fills micron-level gaps. It achieves an IP67 or higher waterproof and dustproof rating. It resists erosion in various automotive environments. This performance meets the strict standards of
Automotive Seal and
Lens Barrel Rubber Seals.
2)Stable Weather and Temperature ResistanceIt can withstand a wide temperature range of -40℃~125℃. In summer, it won’t harden, become brittle, or soften in high-temperature car cabins. In winter, it maintains elasticity in severe cold outdoor environments. It always keeps sealing elasticity. This environmental adaptability meets the durability requirements of Car Camera Silicone Seals and automotive outdoor sealing components.
3)Anti-aging and Medium ResistanceIt has excellent UV and ozone aging resistance. It can withstand common automotive media such as oil stains, glass water, and road cleaning agents. After long-term use, there’s no swelling or degradation. This resistance meets the standards of Automotive Sealing Assemblie and automotive sealing components in complex media environments.
4)Strict Dimensional PrecisionIt is precisely manufactured in accordance with the standards of automotive lens sealing grooves. The inner diameter, wire diameter, and cross-sectional tolerance are controlled at the micron level. After installation, it won’t loosen or shift. It has outstanding adaptability and sealing stability. This precision is like the manufacturing standards of Precision automotive seal and high-precision automotive optical components.
5)Wear Resistance and Vibration ResistanceIts surface is smooth. It has excellent material toughness. It has minimal friction loss with lens components. It can adapt to long-term vehicle jolting and vibration. It maintains structural integrity. This extends the equipment maintenance cycle. This durability matches the service life requirements of Automotive Camera Module Sealing Ring and high-cycle automotive seals.
