A rod wiper sits in the cylinder head to help keep dirt and other foreign material out as the rod moves. Match the rod diameter, wiper groove and mounting profile to the original component.
Nitrile is also known as Buna-N. Match the compound to the specified fluid and service conditions.
Durometer describes material hardness: a higher reading means a harder material on the same scale. It is not a pressure rating.
