1. **What are clamps used for?** They fasten and seal various hoses and pipes to prevent leakage and falling off. 2. **What are the common materials?** 201/304 stainless steel, carbon steel and 35CrMoA alloy steel. 3. **Will 304 stainless steel clamps rust?** They offer good rust resistance under normal conditions, but may rust in highly saline or strongly corrosive environments. 4. **What key parameters should be checked for selection?** Focus on the clamping diameter first, then working pressure, application and pipe type. 5. **Which clamps are suitable for exhaust pipes?** V-band clamps and high-temperature heavy-duty clamps are recommended. 6. **Is it better to tighten the clamp as much as possible?** No. Excessive force may crack the hose or break the screw. 7. **How to prevent clamps from loosening in vibrating environments?** Use anti-loosening & anti-slip clamps and re-tighten them regularly. 8. **Is water leakage always caused by poor clamp quality?** Not necessarily. Hose condition, joint fit and installation also affect sealing performance. 9. **Do you support customized products?** We provide customization on size, material and surface finish. 10. **Do your products comply with European standards for export?** All products can be manufactured to national or European standards for overseas vehicles and equipment.
