Using these hose clips is easy. Just place the clip around the hose where you need it and tighten it properly. Make sure it's secure but don't over - tighten as it might damage the hose. When installing, check that the smooth inner of the clip is in contact with the hose to prevent any abrasion. As for maintenance, since they're made of 18/8 marine - grade stainless steel, they can withstand different conditions. But it's a good idea to regularly inspect the clips for any signs of wear or corrosion, especially if you use your vehicle in harsh environments. If you notice any issues, replace the clips right away. Remember, these clips come with a 12 - month warranty, so if there are any problems within that time, you can get them sorted out. And always use these clips only on AS3 Performance and OEM hoses as they're designed to fit those.
