839

The Hallite 839 double-lip pressure washer is designed to fit standard housings, including many ISO 6195C sizes, and to exclude dirt and moisture from entering the cylinder. The design minimizes oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing through the rod seal.
In front of the wiper lip are two sealing lips precision trimmed at an angle to provide optimum stem sealing performance. The Hallite 839 is designed to have an interference fit in the seal housing groove to improve the stability of the wiper in the bushing and reduce the possibility of ingress around the outside of the wiper.
Hallite 839 is molded in Hythane® 181, Hallite's high-performance polyurethane, for maximum wear resistance.
Hallite recommends that a vent be provided between the seal and the cleaner to avoid a pressure trap.
For customers requiring a cleaner for heavier duty applications, Hallite's technical team may recommend using a Hallite 844 cleaner instead of the Hallite 839. Contact your local Hallite team for more information.
