HIS

The HIS wear rings have been developed in order to keep all parts of the cylinder aligned ( the rod with the head, the piston with the bore).

They play an important role as they help the rod seal, the wiper and the piston seal work without misalignments and at the same time they prevent any contact between the metal parts, The material, which has a very low friction factor, does not cause load losses, (linearity)
