Chesterton CW21K Canned Wiper

The Chesterton CW21K Canned Wiper effectively cleans and dislodge foreign matter from retracting rods or rams, mitigating scoring and system contamination in open cavity designs. These wipers provide excellent performance for hydraulic applications.
Canned wiper seals require an open, easy construction, groove, and help to simplify gland design, layout, and manufacturing.

Less space is required for canned wipers. The canned portion of the seal provides stability due to an interference fit that allows it to be pressed into an open cavity gland design. These wipers are available in various material and size combinations based on equipment requirements, and the canned portion of the seal can be manufactured from metallic material and other engineered plastics.
