Using these hose clips is easy. First, make sure the hose and the connection point are clean. Then, place the clip around the hose at the right position and tighten it properly. When installing, don't over - tighten as it might damage the hose. As for maintenance, these stainless - steel clips are quite durable. But in corrosive environments, it's a good idea to check them regularly for any signs of rust or damage. If you notice any issues, you can use a soft cloth to clean them. Remember, these clips come with a 12 - month warranty, so if you have any problems, you can get in touch with the seller. Also, they're designed to fit all AS3 Performance and OEM hoses, so you don't have to worry about compatibility.
