Hallite® Tipo 844

The design of the Hallite 844 double-lipped, snap-in rod wiper minimises the oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing the rod seal. The Umbrella Wiper Technology™, a unique feature, is a protective debris guard flap on the wiping lip that entirely covers the gland housing and prevents the water/slurry trap that is common with conventional wipers. This feature offers added protection to the integrity of the hydraulic system by reducing corrosion and preventing the ingress of contamination into the wiper housing groove and hydraulic cylinder gland which will result in increased system life.

The standard Hallite 844 is moulded in Hythane® 361, Hallite’s high-performance polyurethane, for excellent durability in service. Some sizes of the Hallite 844 are offered in a Hythane® 181 polyurethane with a textured wiping lip to provide improved dry rod performance, particularly for long stroking cylinder applications.
