Using these hose clips is easy. First, make sure the hose and the area where you'll attach the clip are clean. Then, place the clip around the hose at the right position. Tighten the clip securely, but don't over - tighten as it may damage the hose. As for maintenance, these clips are made of high - quality stainless steel, so they're resistant to corrosion. However, it's still a good idea to check them regularly, especially if you're using the vehicle in harsh conditions. If you notice any signs of wear or damage, replace the clips right away. And remember, these clips come with a 12 - month warranty, so if there are any issues within that time, you can get support.
