This is a High-Quality Automotive O-Ring Seal. It’s a black, regular circular EPDM component. It’s manufactured via peroxide vulcanization. Its hardness is 50°A.It has a highly consistent precision appearance. The ring has a uniformly smooth circular contour. Its thickness is consistent. It has a natural, regular curvature. The surface shows a delicate matte texture. It has a dense, uniform luster from the peroxide process. There’s no discoloration or rough granularity. The edges undergo precision polishing. They are smooth and clean. There are no burrs or defects. Thanks to its 50°A soft hardness, the O-ring maintains structural rigidity. It also reveals elasticity through slight morphological tension. It embodies the dual aesthetic of "precision regularity + gentle elasticity."As a core 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.
1.Function:This high-quality automotive O-ring seal—crafted from EPDM (peroxide vulcanization, 50°A hardness)—serves as the core flexible sealing + precise adaptation component for on-board lenses. Its primary role is to construct an integrated protection system of "seamless fit + stable buffering" for lens installation interfaces.It leverages the O-ring’s annular structural advantage. It uses the density from peroxide vulcanization. It also uses 50°A soft elasticity. It fits the gap between the lens and mounting base tightly. It precisely blocks the intrusion of rainwater, high-pressure car wash water, road dust, moisture, and other contaminants. This prevents fogging of optical lenses, contamination of imaging components, and moisture-induced short circuits. Its flexible elasticity absorbs jolts, vibrations, and high-frequency impacts during vehicle operation. It reduces hard friction at the lens interface.This ensures the imaging accuracy and long-term operational reliability of on-board lenses under complex road conditions and extreme climates. It meets the stable adaptation requirements of "high-quality" sealing solutions. Its dual-functional protection 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)Triple Empowerment of Process + Material + Hardness for Ultimate SealingPeroxide vulcanization achieves uniform crosslinking of EPDM molecules. It forms a dense structure. Combined with 50°A soft hardness, it adaptively fills micron-level gaps at on-board lens interfaces. This achieves IP67-level waterproof and dustproof performance. It resists high-pressure water impact, long-term splashing, and dust adhesion. It also maintains continuous fit through the annular tension of the O-ring. It avoids sealing gaps caused by vibration. Its sealing stability far exceeds that of ordinary O-rings. This performance meets the strict standards of
Automotive Seal and
Lens Barrel Rubber Seals.
2)Flexible Buffering for Complex Automotive Working ConditionsThe 50°A soft hardness endows the O-ring with excellent elastic resilience. It can efficiently absorb high-frequency vibrations and strong impacts from high-speed driving, off-road jolts, and uneven roads. It reduces hard collisions between the lens and mounting base. It prevents displacement of optical components and interface loosening. It is suitable for all scenarios including urban commuting and outdoor off-roading. It protects the lens’s precision structure from damage. This damping performance meets the dynamic requirements of Automotive Camera Module Sealing Ring and automotive optical components.
3)Weather & Aging Resistance for Long-Term Stable QualityEPDM inherently offers excellent weather resistance. It is further enhanced by the peroxide process’s anti-aging properties. It withstands a wide temperature range of -40℃~120℃. It maintains elastic sealing without hardening, embrittling, or becoming sticky/deformed under extreme conditions. This includes high-temperature exposure from summer vehicle baking and low-temperature freezing in winter. It has outstanding UV and ozone resistance. It avoids cracking, embrittlement, and performance degradation during long-term outdoor exposure to sun and rain. It ensures a service life synchronized with that of on-board lenses. This environmental adaptability meets the durability requirements of Car Camera Silicone Seals and automotive outdoor sealing components.
4)Medium & Wear Resistance for Automotive Environment NeedsPeroxide vulcanization improves EPDM’s structural density. It enables resistance to common automotive media such as oil stains, car wash cleaners, and road mud. There’s no swelling, cracking, or performance decline after contact. Despite its softness, the surface exhibits superior wear resistance compared to ordinary flexible seals. It withstands minor friction during installation, disassembly, and daily use. It prevents damage and reduces maintenance costs. This meets the material standards of Automotive Sealing Solution and integrated automotive sealing systems.
5)Precision Adaptation + Easy Assembly for PracticalityAs a high-quality sealing solution, the O-ring features a regular annular contour with zero deviation. Its dimensional precision matches standard on-board lens installation interfaces perfectly. The 50°A softness allows for easy insertion into mounting grooves. No forceful pressing is needed. After fitting, there’s no displacement or missing seals. Its precision-polished, smooth, burr-free edges prevent scratches on lens surfaces or mounting bases during assembly. It safeguards component integrity. This user-friendly design matches the installation requirements of Precision automotive seal and high-precision automotive optical accessories.
