The main function of the Rod Wiper is to keep the rod and cylinder clean and free from foreign matter; thus preventing premature failure. The Rod Wiper is not a pressure sealing element, yet it avoids possible abrasive effects which may result if contaminants were to reach the sealing and rod bearing elements.
Designed for medium duty applications and can provide both wiping and sealing action in one component in low pressure systems. The external lip scrapes foreign matters from the rod, and the other lips act as an effective pressure seal in low pressure applications. This wiper can also be used as a secondary seal to trap slight leakage from the primary seal. This creates a very dry rod system. The WH Rod Wiper is also known as Series 8600.
