Using these hose clips is easy. First, make sure your hose is clean and dry. Then, place the clip around the hose at the right position. Tighten the clip gently but firmly until it holds the hose securely. When it comes to maintenance, since they're made of 18/8 marine - grade stainless steel, they're quite resistant to corrosion. However, it's a good idea to check them regularly for any signs of wear or loosening, especially if you're using your vehicle in harsh conditions. If you notice any issues, replace the clips right away. Keep in mind that these clips are designed to fit specific models of Aprilia motorcycles as mentioned in the product description. Also, they come with a 12 - month warranty, so if there are any problems during this period, you can get in touch with the manufacturer.
