The rod seal works at the cylinder head around the moving rod. Compare the rod diameter, seal outside diameter and groove width, and retain the specified seal profile when selecting a replacement.
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.
