The D wiper is an advancement from the old AN style in the evolution of wipers. The D wiper is superior to the AN style wiper in applications where the rod seal is greater than six inches or where the environment is so contaminated that an AN wiper cannot prevent ingression. High Performance Seals offers four D wiper styles which are all designed to fit the same sized groove, so if application variables change, it is easy to retrofit the existing application with a more advanced design.
This standard D type wiper is designed to replace the AN959 wiper. It's used for large rod diameters. More
