1. Dustproof: CV joint boots can effectively prevent dust, sand, water vapor, and other small particles from entering the CV joint, thereby reducing friction and wear and extending the service life of the universal joint. 2. For front or rear assemblies: CV joint boots can be used for constant velocity (CV) joint boots, ball joint dust covers, dust covers, tie rod ends, and track rod ends. 3. precision: CV joint boots have precise dimensions and reasonable elasticity, allowing them to fit the automotive CV joint snugly and be securely sealed on the exterior of the universal joint without loosening. 4. Durable material: Silicone universal CV joint boots are made of temperatureresistant and wearresistant silicone, which can effectively protect the universal joint from damage caused by external environmental factors.
