Characteristics and performance

The Hallite 851 high-performance rod seal and wiper combination is designed specifically for pneumatic applications and to give significant improvements in cylinder performance in low lube air conditions and be used in long and short stroke applications.

Manufactured in Hythane® 181, Hallite’s high-performance polyurethane, the Hallite 851 is easy to install with excellent low temperature performance and long service life. The material combined with the design of the dynamic sealing lip offers low friction, significantly less than that of a rubber seal, and an ultra-long life.
