DESCRIPTION

The U-HD is a heavy duty metal encased double lip urethane wiper. The double lip design provides optimum contact with the rod to keep out contaminants. When used with a multi-lip sealing system they provide a dry clean rod. 

These wipers are excellent for severe applications and are commonly found in Caterpillar and other heavy-duty off-road equipment.
