The EU Pneumatic seal is a self retaining rod/wiper seal for pneumatic cylinder piston rods. It simultaneously operates the three functions of wiping, sealing and fixing. The sealing lip is geometrically designed to work in oil, air, and vacuum, and made from a synthetic rubber that offers longevity. The geometry of the sealing lip maintains initial lubrication and therefore has excellent friction characteristics, whilst fitting tightly into the groove will ensure reliable operation.
