D.I.D HEAVY DUTY X-RING
D.I.D’S patented X-Ring® construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and 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.
The X-Ring's four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. The D.I.D X-Ring® has the greatest wear resistance of any other type of O-Ring or non O-Ring chain.
