Using these hose clips is easy. Just place them around the hose where needed and tighten them properly. Make sure the clip is firmly attached to prevent any leaks. When it comes to maintenance, since they're made of high - quality stainless steel, they don't need much special care. But it's a good idea to check them regularly for any signs of wear or damage, especially if your vehicle is often in harsh or corrosive environments. If you notice any issues, replace the clips right away. Remember, these clips come with a 12 - month warranty, so if something goes wrong within that time, you can get them replaced or repaired.
