In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

2. Corrosion Resistance Metal covers, particularly stainless steel and galvanized options, are engineered to resist corrosion, especially in environments exposed to moisture and chemicals. This is particularly important in urban areas where road salt, pollutants, and other corrosive elements can significantly affect the lifespan of drainage infrastructure. A corrosion-resistant gully drain cover ensures that the drainage system remains functional and effective over time.
