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 snug but don't over - tighten, as it could damage the hose. When installing, check that the banded edges and smooth inners are in good contact with the hose for the best protection. As for maintenance, since they're made of 18/8 marine - grade stainless steel, they're resistant to corrosion. But it's still a good idea to clean them regularly, especially if they're exposed to harsh environments. Just use a mild cleaner and a soft cloth. If you notice any signs of damage or wear, it's best to replace the clips. And remember, these clips come with a 12 - month warranty, so if you have any issues, you can get in touch with the manufacturer.
