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 appropriate position. Tighten the clip gently until it fits snugly, but don't over - tighten as it might damage the hose. As for maintenance, since they're made of high - quality stainless steel, they can resist corrosion well. However, it's still a good idea to check them regularly, especially if you use your vehicle in harsh environments. If you notice any signs of wear or damage, replace the clips right away. Remember, these clips come with a 12 - month warranty, so if there are any issues within this period, you can get them sorted out easily.
