Using these hose clips is easy. First, find the right hose that fits your Beta Evo 80. Then, place the clip around the hose where it needs to be attached. Make sure it's snug but don't over - tighten it as it could damage the hose. When it comes to maintenance, these clips are made of high - quality stainless steel, so they're resistant to corrosion. However, it's a good idea to check them regularly, especially if your vehicle is used in harsh or corrosive environments. If you notice any signs of wear or damage, replace the clip right away. Also, keep in mind that these clips are designed for specific hoses, so always use them with AS3 Performance or OEM hoses for the best results. And remember, the warranty is for 12 months, so if you have any issues during that time, you can get it sorted out.
