The Hallite 839 wiper is precision moulded in Hallite's high performance polyurethane - Hythane 181 for maximum wear resistance, and is designed to exclude dirt and moisture from entering the cylinder and to collect traces of fluid passing the rod seal.Opposite the wiper lip are two sealing lips accurately produced and proportioned to collect fluid passing the rod seal. To obtain stability and improve the seal the outside diameter is in interference with the housing.The Hallite 839N wiper is designed to suit popular Asian housing and has a textured wiping lip for improved performance. A vent between the seal and the wiper is recommended to avoid a presure trap.
