Using these hose clips is easy. Just place them around the hose where you need to secure it. Make sure the clip is tightened properly but don't over - tighten as it may damage the hose. When installing, check that the smooth inner part of the clip is in contact with the hose to protect it. For maintenance, since they are made of stainless steel, they are resistant to corrosion. However, it's a good idea to regularly check the clips for any signs of wear or looseness. If you notice any issues, replace the clip promptly. Keep in mind that these clips are designed to fit specific models and hoses, so always use them with compatible parts. Also, remember that the warranty covers normal use, so avoid using the clips in extreme conditions that are not recommended.
