Available in categories 0, A, B, C, D
TIP: Category 0 is usually installed in almost all cylinders ex works.
With a higher mileage of the cylinder or to achieve a tighter running clearance, a piston of the next higher category can also be selected (e.g. cylinder = 0, piston = A or cylinder = A, piston = B).
A category size corresponds to the dimensional increase on the piston by 1/100mm.
