1. For the front or rear assembly: The foodgrade connecting boots can be used for constant velocity (CV) joint boots, ball joint dust covers, dust covers, tie rod ends, and track rod ends. 2. Durable material: The universal silicone CV joint boots are made of temperatureresistant and wearresistant silicone, which can effectively protect the universal joint from damage caused by external environments. 3. Practical and functional: CV joint boots can effectively prevent dust, sand, water vapor, and other small particles from entering the CV joint, reducing friction and wear while extending the lifespan of the universal joint. 4. precision: The CV joint boots feature precise dimensions and reasonable elasticity, ensuring a fit into the automotive CV joint and a secure, tight seal on the exterior of the universal joint without loosening.
