The use of Polyurethane with it’s excellent properties combined with the proportioned design of the wiper will extend the service life of the rod seal.Claron Wiper Seals Style PWD should not be utilised in combination with double-acting Rod seals unless the housing design allows for pressure relief between the wiper and the seal.
