Using these hose clips is easy. Just open the clip and place it around the hose where you need it, then close it securely. When installing, make sure the clip is centered on the hose to get the best hold. As for maintenance, since they're made of marine - grade stainless steel, they're resistant to corrosion. But it's still a good idea to check them regularly for any signs of wear, especially if you're using the vehicle in tough conditions. If you notice any damage, replace the clip right away. Remember, these clips are designed to fit AS3 Performance and OEM hoses, so don't try to use them with incompatible hoses. And keep in mind that they come with a 12 - month warranty, so if there are any issues within that time, you can get them sorted out.
