The 839 type double-lipped, snap-in wiper is designed to fit standard housings, including many ISO 6195C sizes, and to exclude dirt and moisture from entering the cylinder. The design minimises the oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing the rod seal. Opposite the wiper lip are two sealing lips that are precision trimmed at an angle to give optimal rod sealing performance. The 839 is designed to have an interference in the seal housing groove to improve the stability of the wiper in the gland and to reduce the possibility of ingress around the outside of the wiper. The 839 is moulded in Hythane 181, Hallite's high-performance polyurethane, for maximum wear resistance.
