Rod seals are particularly exposed to pressure and friction and a long service life is a specific requirement of piston rods. Zurcon® U-Cup RU9 can offer this with its outstanding wear and extrusion resistance. It is also compatible with virtually all media, has a wide operating temperature range, and gives low friction. It has compact installation dimensions, is easy to assemble and can be used as a stand alone element with limitation to 40 MPa or in a tandem system with pressure up to 50 MPa.
