622

The Hallite 622 is a top-of-the-range twin lip rod seal designed to provide a dry sealing solution in light and medium-duty applications.

The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the precision trimmed primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures.

This unique profile is also used in the Hallite 621 twin lip rod seal and its seal shell is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. The Hallite 622 is also offered in other high quality Hythane® materials to match the needs of the application.
