Using these hose clips is easy. First, identify the hoses on your 2017 - 2019 KTM 450 or 500 EXC where the clips need to be installed. Make sure the hoses are clean and dry before you start. Then, place the clip around the hose and tighten it properly. When tightening, be careful not to over - tighten as it might damage the hose. These clips are made of high - quality 18/8 marine - grade stainless steel, so they're resistant to corrosion. But to keep them in top shape, regularly check for any signs of wear or looseness. If you notice any issues, replace the clips right away. Since they're made in the UK and come with a 12 - month warranty, you can contact the manufacturer if you have any problems within this period.
