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 prevents possible abrasive effects which may result if contaminants were to reach the sealing and rod bearing elements.
One-piece snap-in type rod wiper scrapers for heavy duty applications. (ST) wipers are continuous (not split) and conform with wear and side motion for effective wiping action over the entire life span of the seal.
Designed for light duty applications where style ST wipers are not required. Interchangeable with corresponding dash numbers of MS28776 wiper rings.
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.
Double lip design provides the ultimate in wiper action to remove foreign material from the exposed rod while still maintaining an adequate lubricating film. It protects both the rod and the primary seal.
