Product details

This is an O-Ring Seal dedicated to vehicle-mounted cameras. It is made of silicone via compression molding process. Its hardness is 40±5°A. It is a black silicone component featuring a circular ring shape. Its thickness is uniform. Its contour is smooth.Benefiting from the low-hardness property of 40±5°A, it exhibits excellent soft elastic tension. The component is free of burrs and defects. It boasts precise and consistent dimensions. It perfectly fits the sealing mounting grooves of vehicle-mounted cameras.As a core sealing accessory for automotive optical systems, it complies with the stringent standards of Automotive Seal and Precision automotive seal. It is fully compatible with the application requirements of Car Camera Silicone Seals and Automotive Camera Module Sealing Ring.

Product Features

1.Functions

1)Sealing and Protecting Vehicle-Mounted CamerasIt fills the gaps between the vehicle-mounted camera housing and the mounting base. It blocks outdoor contaminants such as rainwater, dust, and silt from entering the camera interior. This protects precision components like lenses and image sensors. It prevents pollutants from impairing imaging clarity or causing short-circuit damage to components. This sealing performance meets the rigorous demands of Precision Seals for Car Lenses and Lens Barrel Rubber Seals for automotive optical devices.

2)Buffering and Shock AbsorptionIt leverages the soft elasticity of low-hardness silicone. It cushions vibrations and bump impacts during vehicle operation. It reduces mechanical wear between the camera and its mounting position. It minimizes the interference of vibrations on imaging stability.

3)Adapting to Installation TolerancesThe low-hardness property enables it to accommodate minor tolerances on the mounting surface of vehicle-mounted cameras. It closely fits gaps in different installation scenarios. It compensates for dimensional deviations caused by processing and assembly. It ensures consistent sealing performance.

2.Performance Characteristics

1)Sealing Adaptability of Low-Hardness SiliconeIt is made of 40±5°A low-hardness silicone. It is softer than high-hardness seals. It enables better adhesion to irregular or slightly toleranced mounting surfaces. It more fully fills gaps. It delivers more reliable sealing effects. Meanwhile, the compression molding process ensures precise dimensions. It ensures uniform structure. It ensures no splicing defects of the components.

2)Environmental Resistance of Silicone MaterialSilicone boasts excellent temperature resistance (adaptable to the temperature variation of -40℃~80℃ in automotive environments), aging resistance, and UV resistance. Long-term exposure to outdoor sunlight and rain will not cause aging phenomena such as hardening, embrittlement, or stickiness. It matches the long service life requirements of vehicle-mounted cameras. This durability aligns with the standards of Automotive Sealing Assemblie and long-service automotive components.

3)Consistency Ensured by Compression Molding ProcessIt is mass-produced via compression molding. The components feature highly consistent performance parameters such as dimensions, hardness, and elasticity. It avoids individual differences caused by manual production. It ensures uniform sealing effect of each O-ring. It meets the standardized assembly requirements of automotive accessories. This consistency complies with the quality standards of Automotive Sealing Solution and integrated automotive sealing systems.

3.Application Scenarios

1)Various Vehicle-Mounted CamerasIt is suitable for the housing sealing and lens base sealing positions of vehicle-mounted vision devices such as dashcam cameras, reverse image cameras, and 360° panoramic image cameras.

2)Outdoor Vehicle-Mounted Installation ScenariosIt is ideal for cameras installed in outdoor exposed positions of automobiles, such as front/rear bumpers, rearview mirrors, and roof racks. It is especially applicable to automotive environments requiring dustproof and waterproof performance (IP65/IP67 rating).

3)Commercial and Passenger Vehicle CamerasIt covers the sealing needs of vehicle-mounted cameras for different vehicle types including passenger cars, trucks, and ride-hailing vehicles. It adapts to the operating conditions of vehicles with high-frequency vibrations and frequent temperature changes.

4.Pain Point Solutions

1)Solving Outdoor Contamination Problems of Vehicle-Mounted CamerasOrdinary high-hardness seals are difficult to fit the minor gaps on automotive mounting surfaces. This may lead to rainwater and dust entering the camera interior. It may cause blurred imaging or component damage. This low-hardness silicone O-ring can tightly fill gaps. It effectively isolates outdoor contaminants.

2)Addressing Wear and Imaging Interference Caused by VibrationVibrations during vehicle operation are prone to cause mechanical wear between the camera and its mounting position. It may interfere with imaging stability at the same time. The buffering and shock absorption function of low-hardness silicone can reduce wear. It can minimize the interference of vibrations on imaging.

3)Resolving Sealing Failure Caused by Installation TolerancesMinor tolerances are likely to occur during the processing and assembly of automotive accessories. Ordinary seals are difficult to adapt to these tolerances. It results in poor sealing of some cameras. This low-hardness O-ring can self-adapt to tolerances. It ensures consistent sealing performance in different installation scenarios.

4)Eliminating Aging Failure Problems in Outdoor EnvironmentsOrdinary rubber seals are prone to aging and failure due to sunlight and temperature changes in automotive outdoor environments. They require frequent replacement. The aging resistance of silicone material can extend the service life of the O-ring. It can reduce maintenance costs.
