This is an Automotive Sealing Assemblie-EPDM Sealing Ring. It’s a black rectangular rubber component.It has a regular rectangular contour. The corners are rounded. Its surface is delicate and matte. There are no redundant textures. Its cross-sectional thickness is uniform. Its edges are flat and rounded. There are no burrs. Its dimensional precision is high. This lets it fit accurately into the grooves of automotive sealing assemblies. It serves as a key small-sized sealing accessory. It ensures the waterproof and dustproof performance of on-board components.As a core part of integrated automotive sealing systems, it perfectly meets the technical standards of Automotive Sealing Solution and Precision automotive seal. It is compatible with the application scenarios of Car Camera Silicone Seals and Lens Barrel Rubber Seals.
Product Features
1. Function:This EPDM rectangular sealing ring is a key "protective guard" in the automotive sealing assembly system. It is specifically designed for various rectangular sealing interfaces of automobiles (such as on-board sensor interfaces, electronic module housing joints, small hydraulic component connections).It embeds tightly into rectangular sealing grooves. It forms a high-airtightness barrier. It completely blocks the invasion of external contaminants such as rainwater, dust, sand, and road splashed moisture. This avoids short circuits of on-board electronic components and corrosion of mechanical parts. It also prevents leakage of automotive internal oil and gas. This ensures the stable operation of power systems and electronic systems.It maintains sealing reliability for automobiles under all working conditions such as rainy days, sandstorms, high-temperature exposure, and severe cold freezing. It fundamentally safeguards the service life and performance precision of components. Its comprehensive protective function matches the requirements of Automotive Camera Module Sealing Ring and Precision Seals for Car Lenses in automotive multi-scenario applications.
2. Performance Characteristics
1)Superior Sealing PerformanceIt’s made of EPDM with excellent elastic recovery capability. It can fill micron-level gaps in rectangular sealing grooves tightly. It achieves an IP67 or higher waterproof and dustproof rating. Even under dynamic working conditions such as long-term vehicle vibration and thermal expansion and contraction, it can keep the sealing surface fitted continuously. It resists extreme tests such as high-pressure water spraying and sand intrusion effectively. This performance meets the strict standards of Automotive Seal and Automotive Sealing Assemblie.
2)Extremely Wide Weather and Temperature Resistance RangeIt can work stably in environments from -40℃ severe cold to 125℃ high temperature. The high temperature of the automotive engine compartment in summer won’t make it harden, become brittle, or soften and deform. The freezing weather outdoors in winter also won’t affect its performance. It always maintains good sealing elasticity. It adapts to the all-region and all-season usage scenarios of automobiles. This environmental adaptability meets the durability requirements of Car Camera Silicone Seals and automotive outdoor sealing components.
3)Strong Anti-aging and Medium CompatibilityIt has excellent UV and ozone aging resistance. Even after long-term exposure to outdoor sunlight, it won’t crack or degrade. It can withstand the erosion of various chemical media such as automotive engine oil, transmission oil, coolant, glass water, road salt spray, and cleaning agents. After immersion, there’s no swelling or material deterioration. The sealing performance remains stable for a long time. This compatibility meets the material standards of Automotive Sealing Solution and integrated automotive sealing systems.
3)Micron-level Dimensional Precision ControlIt’s precisely molded based on the CAD data of automotive rectangular sealing grooves. The dimensional tolerances of length, width, and cross-section are strictly controlled within ±0.05mm. It ensures "zero-gap" fit with the sealing groove. After installation, it won’t loosen or displace. Even under long-term vehicle jolting, it can maintain the stability of the sealing position. It adapts to the standardized and customized sealing needs of different brands and models of automobiles. This precision is like the manufacturing standards of Precision automotive seal and high-precision automotive components.
4)Wear Resistance, Vibration Resistance, and Long Service LifeThe rubber surface is smooth with a dense molecular structure. It has a low friction coefficient. When in contact with automotive metal and plastic components, the wear rate is minimal. The material has excellent toughness. It can absorb high-frequency vibrations during automobile driving. This avoids loosening of the sealing surface caused by vibration. It significantly extends the replacement cycle of the sealing ring. It reduces the later maintenance cost of the automobile. This durability matches the service life requirements of Automotive Camera Module Sealing Ring and high-cycle automotive seals.
