D Style Wipers

The D wiper is the next step in evolution of wipers from the old AN style .  D wipers are better than AN style wipers in applications where the rod seal is larger than 6 inches or where the environment is sufficiently contaminated that an AN wiper fails to prevent ingression.  RT/Dygert offers four styles of D wipers below that are all designed to fit the same sized groove such that, if application variables change, it is easy to retrofit an existing application with a more advanced design.
