Understanding This Part
- Material code URE: urethane

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.
Urethane is a sealing material valued for resistance to abrasion and cutting.
Durometer describes material hardness: a higher reading means a harder material on the same scale. It is not a pressure rating.
