The purpose of the profile double lip wiper is to prevent dust, dirt, grains of sand, and metal swarfs. This is achieved by a special design which largely prevents scoring, protects the guiding parts and extends the service life of the seals. In addition, the sealing lip facing the media reduces the residual oil film. The profile AY double wiper ring closes the rod in the direction of the cylinder. No special screwrings or brackets are required for installation. No close tolerances and no metal inserts are required. The wiper is supplied as a continuous ring and can easily be pressed into the groove. The polyurethane compound ensures excellent properties with regard to dry run, increased wear resistance, and extended service life due to good resistance to ozone and radiation caused by weather conditions. We recommend profile double-lip wiper when using PTFE rod seals or whenever the residual oil film is to be kept at a minimum.
