Product Features

1)Sealing Protection for Vehicle-Mounted LensesIt precisely fills the mating gaps between vehicle-mounted lenses and housings. It also fills gaps between lens modules and mounting bases. It effectively blocks rainwater, silt, dust and in-vehicle condensation from entering the lens interior. It protects core precision components such as lenses and image sensors. It prevents blurred imaging and lens short-circuit faults caused by contaminant adhesion or moisture condensation. This sealing performance meets the rigorous demands of Precision Seals for Car Lenses and Lens Barrel Rubber Seals for automotive optical devices.

2)Buffering, Shock Absorption and Anti-ShakeIt leverages the elastic properties of EPDM material. It cushions high-frequency jolts and vibration impacts during vehicle operation. It reduces mechanical wear between the lens and its mounting position. It minimizes the interference of vibration on the lens anti-shake performance. It ensures the stability of driving images.

3)Adapting to Lens Assembly TolerancesThe 50±5°A hardness balances elasticity and rigidity. It allows the O-ring to self-adapt to minor dimensional deviations in the processing and assembly of vehicle-mounted lenses. It ensures consistent sealing fit for lenses of different batches. It maintains sealing reliability under all working conditions.

 

1)EPDM + Peroxide Vulcanization Process for Resistance to Complex Automotive EnvironmentsIt is based on EPDM ethylene-propylene-diene monomer rubber substrate. It is combined with peroxide vulcanization process. It significantly enhances weather resistance and heat resistance. It is capable of withstanding the wide automotive temperature range of -40℃~150℃ for a long time. This range covers low temperatures in winter to high temperatures in engine compartments in summer. It also boasts excellent UV and ozone resistance. Even when the lens is installed on exterior vehicle parts (such as bumpers and rearview mirrors), long-term exposure to sun and rain will not cause aging problems such as hardening, embrittlement and deformation. It matches the long service life requirements of vehicle-mounted lenses. This durability aligns with the standards of Automotive Sealing Assemblie and long-service-life automotive components.

2)High-Precision Dimensions for Precision Assembly of Vehicle-Mounted LensesThe outer diameter is strictly controlled at 23.2±0.10mm. The cross-sectional diameter is accurate to 1.65±0.05mm. The minimal dimensional tolerance enables perfect matching with standardized sealing grooves of vehicle-mounted lenses. It avoids poor sealing or assembly jams caused by dimensional deviations. It meets the precision assembly requirements of vehicle-mounted lens modules. This precision complies with the quality standards of Automotive Sealing Solution and integrated automotive sealing systems.

3)50±5°A Hardness Balancing Sealing Performance and DurabilityThe medium-low hardness setting retains sufficient elasticity. It allows the O-ring to tightly fit the micro-gaps on the lens sealing surface. It achieves IP67 or higher dustproof and waterproof sealing. It also has a certain structural rigidity. It prevents excessive deformation under working conditions such as frequent lens disassembly and long-term extrusion. It extends the service life of the sealing component.

4)Excellent Medium Resistance for Multi-Scenario Contact Needs in VehiclesEPDM material has excellent resistance to common automotive media (such as windshield washer fluid, car wash liquid and weakly alkaline cleaning agents). There is no swelling or degradation after long-term contact. It can also withstand slight oil contamination and moisture erosion in the vehicle. It adapts to both internal and external installation scenarios of vehicle-mounted lenses.

 

1)Lenses for Automotive Vision SystemsIt is suitable for sealing the housings and modules of 360° panoramic imaging lenses, reverse image cameras and dashcam lenses. It covers the installation needs of various vehicle-mounted lenses for passenger cars and commercial vehicles.

2)External Vehicle-Mounted Lens ScenariosIt is ideal for sealing lenses installed in outdoor exposed positions of vehicles such as bumpers, rearview mirrors and roofs. It withstands harsh environments such as sun exposure, rain and sandstorms.

3)Internal Vehicle-Mounted Lens ScenariosIt can be used for interface sealing of in-vehicle DMS driver monitoring lenses and OMS occupant monitoring lenses. It blocks condensation and dust intrusion inside the vehicle.

 

1)Solving Outdoor Sealing Failure Problems of Vehicle-Mounted LensesOrdinary rubber O-rings are prone to rapid aging and embrittlement due to UV and ozone erosion in outdoor automotive environments. This leads to rainwater and dust entering the lens interior. This EPDM + peroxide process O-ring has strong weather resistance. It enables long-term stable sealing. It greatly reduces the probability of lens faults.

2)Resolving Lens Sealing Leakage Caused by Dimensional DeviationsVehicle-mounted lenses have extremely high requirements for assembly precision. Ordinary O-rings with large dimensional tolerances are prone to mismatching with sealing grooves. This causes moisture leakage. The high-precision dimensional control of this O-ring enables precise adaptation to lens sealing grooves. It eliminates sealing failure caused by dimensional factors.

3)Addressing Unstable Lens Imaging Caused by VibrationHigh-frequency vibrations during vehicle operation are likely to cause lens loosening and poor fit of sealing components. They also interfere with imaging stability. The elastic buffering effect of this O-ring can reduce the impact of vibration on the lens. It ensures clear and stable images.

4)Solving Poor Adaptability to Lens Assembly TolerancesThere are minor tolerances in the processing and assembly of vehicle-mounted lenses of different batches. Ordinary sealing components are difficult to meet the fitting requirements of all specifications. The balanced hardness and elasticity of this O-ring can self-adapt to tolerance deviations. It improves the compatibility and yield rate of lens sealing.
