103-2140/04438-16080/04427-0K020 Elastic Rubber CV Joint Dustproof Protective Boot

Technical Parameters
Material Technology: Made from highly durable elastic rubber material, the product features excellent tear resistance, wear resistance, and oil resistance. It can withstand long-term contact with grease and exposure to complex road environments while maintaining reliable sealing performance.
Sealing Structure: Featuring a multi-fold flexible expansion design, the dust boot can accommodate axial displacement and angle changes generated during drive shaft operation. It continuously maintains close contact with the outer surface of the C.V. joint during movement, minimizing sealing gaps.
Protection Performance: The reinforced covering structure effectively prevents external dust, mud, moisture, and particles from entering the interior of the constant velocity joint, protecting precision transmission components such as steel balls and raceways.
Lubrication Protection: The product maintains a stable internal grease storage environment, reducing lubricant leakage and drying, allowing the C.V. joint assembly to maintain proper lubrication performance during long-term operation.

Core Advantages
Excellent Dustproof Sealing Capability: Through a high-fitting structural design, the product effectively blocks external contaminants from entering the C.V. joint, preventing dust and abrasive particles from damaging precision moving surfaces and improving drivetrain reliability.
Flexible Adaptability: The rubber material provides excellent flexibility, allowing the protective boot to naturally expand and contract with vehicle steering, suspension movement, and drive shaft operation, reducing the risk of cracking caused by repeated deformation.
Enhanced C.V. Joint Protection: The dustproof boot not only provides sealing protection but also acts as a buffer layer, reducing the possibility of direct impact from road debris or external forces on the C.V. joint surface.
Extended Maintenance Intervals: By maintaining a stable lubrication environment and reducing contamination entry, the product helps minimize abnormal wear of the C.V. joint and reduces maintenance costs caused by frequent component replacement.
Accurate Application Matching: Designed according to different installation positions, inner and outer C.V. joint boots vary in dimensions, expansion range, and load characteristics. This product is developed according to specific specifications to prevent installation issues caused by incorrect matching.

Application Range
Protection of inner and outer constant velocity joints in automotive front-wheel-drive systems;
Drive shaft repair and C.V. joint assembly maintenance applications;
Drivetrain systems of passenger cars, SUVs, and light commercial vehicles;
Vehicles requiring long-term protection against dust, mud, water, gravel, and other challenging road conditions.
