Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.
