21K Wiper

The Chesterton 21K is a robust, positive-rake lip wiper engineered to protect rods and rams from dirt, moisture, and abrasive debris during retraction. Its aggressive lip profile effectively cleans the shaft surface, preventing scoring and stopping contaminants from entering sensitive systems, which helps extend the life of equipment and maintain operational efficiency. Constructed from highly abrasion-resistant materials and featuring a convenient split design, the 21K can be installed without full disassembly, providing a tight seal against a wide range of contaminants. It performs reliably in demanding industrial environments, including manufacturing, mining, and fluid power systems. With a speed rating of up to 0.9 m/s and a temperature capability from –50 °C to 85 °C, the 21K ensures consistent performance, durability, and protection for critical components under challenging operating conditions.
