D.I.D's patented X-ring construction reduces friction by twisting between the side plates instead of being squashed. Other makers modified O-rings have squashed points that increase friction. The twisting action of the X-ring disperses the pressure and minimizes power loss, while the four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-ring. X-rings have the greatest wear resistance of any other type of O-ring or non-O-ring chain.
