Wiper - Types 839/840

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 pressure trap. The Hallite 840 medium to heavy duty rod wiper is designed to remove heavy deposits of mud, ice and similar contaminants from the rod. The proportions of the knife trimmed wiping lip ensure it remains in contact with the rod at all times, even where severe side loads exist. The main body features a rib to prevent moisture and other contaminants from passing over the outside diameter. This product is manufactured from Hallite’s high performance polyurethane - Hythane® 181- to provide a flexible responsive wiper with excellent resistance to abrasion.
