- Component Inspection: Before installing waterproof nuts, carefully inspect the nuts, bolts, and connected components for damage, burrs, and other defects. These defects may affect the sealing performance and ease of installation. Defective components should be repaired or replaced promptly.
- Surface Cleaning: Ensure the surfaces of the nuts, bolts, and connecting parts are clean and free of oil, dust, and other impurities. Oil and dust can affect the sealant's fit to the component surface, reducing the waterproofing effect. Clean the surface with a clean cloth or a specialized cleaner, then air dry with dry air.
- Selecting the Appropriate Waterproof Nut: Select waterproof nuts with appropriate specifications, materials, and sealing types based on the actual use environment and connection requirements. Different applications require different waterproofing grades, temperature resistance, and chemical resistance. For example, in high-temperature environments, waterproof nuts made of heat-resistant materials should be selected; in environments subject to acid and alkali corrosion, nuts with acid and alkali resistance should be selected.
