How to read the size
A seal size is given as three numbers. On elements fitted to the rod the order is inner diameter × outer diameter × height; on elements fitted to the piston it is outer diameter × inner diameter × height — so the order of the numbers itself tells you where the element sits. A divided third number such as 7/5 gives the heights of the two lips on double-lip wipers.
