The wiper series is used primarily in reciprocating applications as a dirt excluder. Our most popular wiper is the WPB style. The WPB series is normally produced with a ground O.D. and 90-durometer nitrile material.

The W series is used in applica-tions subject to wide variances in thermal expansion or for press fitting into a housing where installation is difficult.

The agricultural designs are multi-lipped pre-lubed seals used in conjunction with wear sleeves to prevent dirt from entering the system.

This series is to be used for large shaft to bore misalignment or excessive dynamic run-out.
